The market
While notebook prices fall and technological advancements narrow the performance gap between desktop and mobile PCs, consumers will still pay the price for portability, with notebooks being significantly more expensive than a desktop PC - and harder to upgrade.
Lesser known brands are now accounting for more and more of the notebook market, but HP/Compaq, Toshiba, Dell, Lenovo (formerly branded IBM), Acer and Australia's own Optima remain brand names that people respect.

Which extras can be included?
Which extras can be included?
A few final items are worth considering. If you are going to be using your notebook on the move, ask about extra batteries as well as items such as carrying cases.
Also, consider whether there will be extras that are bundled cheaply at the time of buying, such as USB TV tuners, USB flash memory keys, optional upgrades and more.
If you think you will want to increase the amount of RAM later, then perhaps it is worth considering upgrading it at the time of purchase, saving both time and money. It is common for retailers to offer to upgrade the amount of RAM at a cheaper price or even for free during promotions.

How can I tell if the software is legal?
How can I tell if the software is legal?
One of the biggest concerns with bundled software is whether you're getting the genuine article.
Microsoft has established a licensing section on its Web site dedicated to protecting users from pirated copies of its software products.
According to the Microsoft site, the best way for you to confirm that the software you have been given with your PC or notebook is authentic Microsoft software, is to first check your end user license agreement (EULA). If you have purchased your PC from a retail outlet and have been given the software with it, check the Microsoft license pack and look for the certificate of authenticity (COA) on the box.
Alternatively, if the software has already been installed on the PC, look for the COA which accompanied the product. For OEM products, the COA is either on a separate page or affixed as a label to the PC chassis.
Open license customers can view their electronic purchase history via the Microsoft Web site. This site also maintains a free software inventory analyser, which can tell you what Microsoft products you have loaded on your PC. For more information on these, check out the Microsoft website
Besides the operating system, PC or notebook buyers may also receive a range of other software products either bundled with or pre-installed on their system, including reference, business or education programs.
For more general information on pirated software, the BSAA (Business Software Association of Australia) has compiled consumer guides on what to look out for when purchasing PC software. These not only cover new software, but also look at purchasing new or second-hand software online. More information is available on their website
The site also provides links to piracy statements from a variety of software providers, such as Macromedia, Symantec, Autodesk and Adobe. All such sites advise users to purchase their PC and related software from a reputable reseller, and to check that all software comes with authentic packaging and a license agreement. Even if the software has already been pre-installed on your PC or notebook, the reseller should still provide you with a software license agreement. You should also receive the original software discs and manuals for all the pre-installed software. Users can also seek further information on anti-piracy laws and report suspected pirated software to the Software and Information Industry Association (SIIA). The trade organisation has over 800 member companies from the software and Internet industry worldwide.

Most notebooks come with either Windows XP Home or Professional pre-installed, but a few vendors will also let you opt to have Linux preinstalled. When buying a notebook, you may pick up some real bargains in bundled software, including utilities, backup software (either Nero or Easy Media Creator), productivity software (such as Microsoft Works or an office suite) and sometimes multimedia (DVD/CD) creation software and even games.

Questions to ask the retailer
Questions to ask the retailer
Free leather carry bags, bundled software, extended warranty, accidental damage cover and the like are often nice value-added features. But if the machine isn't good value without them, think again.
Top 10 questions to ask regarding warranty
Even the most reliable machines may experience faults that cannot easily be rectified. Repairing a notebook can be extremely expensive - unlike equivalent desktop machines, manufacturers are more likely to use non-standard components. Even if this is not the case, replacing many parts is too complex for the average user. The majority of manufacturers offer one-year return-to-base warranties. Some offer to collect your machine as part of the standard warranty, most will be willing to extend terms at a price, and a few manufacturers offer three years of support. It's also worth noting that it's common practice for notebook vendors to use professional third-party support contractors, especially where the vendor doesn't have a repair centre in your city or state.
Is there a guaranteed turnaround time on service or an option to pay to include this? This applies to return to base or courier pick-up warranties.
If you live in a regional area, does the "free courier pickup" warranty still apply to you?
Is the warranty International? If so, what countries and locations are included? This is one to keep in mind if you're a regular traveller.
Can you get a courtesy notebook if there are extended repair problems?
If you're a business, is there an option to sign a service agreement contract?
What are the warranty specifics concerning dead display pixels?
If the notebook is being shipped to you, is transit damage insurance included?
What is the warranty on the notebook's battery?
Are parts and labour included in the warranty?
Are any third-party support contractors sufficiently stocked with parts and sufficiently trained to support your particular notebook model?

Battery
Battery
If you expect to use your computer on the move, battery life is an important consideration. All notebooks now use rechargeable lithium ion (Li-Ion) batteries, which currently offer the best performance of the commercial battery technologies in common use.
The performance of a Li-Ion battery is judged by its capacity, which is measured in cells.
Most notebook vendors will offer a variety of optional battery upgrades (batteries with around 6-12 cells) or even a second battery for when travelling (for around $200).
A word of warning: many notebook warranties that may go for one or even three years will still only cover the battery for six months.
Also, don't forget that high power processors, plenty of RAM and fast disk drives will devour battery life. If you will frequently be operating your notebook on its battery power, you may want to investigate your processor, notebook and operating system's various power-saving options.

Sound
Sound
Sound quality continues to be an afterthought for many notebook vendors with barely minimum quality sound chips and tinny built speakers - but things are slowly improving.
Intel's reference design for its Centrino platform gives notebook manufacturers the choice to include Intel Hi-Definition audio that supports DTS, THX and Dolby technologies for up to eight channels at 192kHz/32-bit quality.
In addition, some notebook vendors are including optical or S/PDIF audio-outputs built-into their machines as standard while others are including underside sub woofers, four speaker configurations, integrated brand name speakers and more in order to improve sound quality.
If you love the idea of a notebook, but audio quality is important to you professionally or personally, then rest assured that there are also many USB, FireWire and PC Card external sound card options available.

Peripheral connectivity
Peripheral connectivity
All computers, particularly notebooks, need to be connectable. Some notebooks feature older PS/2 and serial legacy ports, but these days many don't. The reason for this is because most peripherals (such as keyboards and mice) now connect via USB 2.0 or FireWire.
Some notebooks have a single FireWire connection (enabling peripherals like video cameras to connect at approximately 400Mbps) but nearly every new notebook will have around three USB 2.0 ports, while older notebooks will have approximately two USB 1.1 ports.
Also known as Hi-Speed USB, USB 2.0 allows data transfer at 480Mbps (instead of USB 1.1's 12Mbps).
Another common task is to connect an external monitor using a notebook's VGA-out port.
PC Cards are a notebook's equivalent of a desktop computer's PCI slot - both are used for expanding a machine's capabilities by introducing new hardware. PC Cards are shaped just like a card and have for years been the preferred means of connecting notebooks with add-ons such as sound cards, extra ports and more. However, now PC Cards are making way for a smaller, faster, and more desktop-friendly format called ExpressCard.
Members of the PCMCIA (Personal Computer Memory Card International Association) - the trade group responsible for PC Card standards - introduced the first ExpressCard modules in 2004 in part to meet PC industry demands for smaller PC Cards for today's shrinking portables.
The notebook transition to ExpressCards has already begun: a few notebooks in the $3000-range such as Lenovo's ThinkPad T43 are shipping with both CardBus and ExpressCard slots. PCMCIA officials expect that in 2006, 70 per cent of new notebooks will ship with ExpressCard slots - and no CardBus slots. ExpressCard peripherals should begin appearing in stores around Christmas 2005.

Removable storage
Removable storage
CD/DVD: These days, a CD-burner/DVD-ROM combination drive is pretty-much standard on all new value-orientated (approximately sub $2500) notebooks. It's only in rare instances or older machines that you encounter a CD-ROM only notebook. For this reason and because of the rise in popularity of USB flash drives, integrated floppy disk drives are becoming more rare, although are still normally available as internal or external USB options. Most mid- to high-end notebooks ($3000 and above) now feature DVD-writers that can burn and playback DVDs and CDs. That said, notebook vendors usually let you customise what type of drive you would like and this of course, will affect the price. If you can see yourself only requiring small backups here and there, then you can save money by going for just a CD burner or CD-burner/DVD-ROM combination drive. You could always get an external USB or FireWire drive at a later date. If you're notebook has a modular (easily swappable/replaceable) drive, you could also order a new compatible drive from your vendor and swap it in yourself. If your notebook's drive isn't swappable it's what's known as a fixed drive, which means your better off getting the best drive you can afford at the time of purchase.
Media card readers: Many notebooks now feature built-in media card readers that are perfect for a variety of uses such as getting images from your camera into your notebook. Multiple formats are often supported, including Secure Digital (SD), MemoryStick, MultiMediaCard, xD, CompactFlash, Smart Media and MicroDrive.
External hard disks: A great way to meet big removable and transportable storage needs is to use an external hard disk. They can connect to your PC via USB, FireWire or even be a MicroDrive hard disk or even PC Card hard disk (such as those made by Toshiba).
Other: Jaz, Zip, Rev or tape drives that connect via USB, parallel port or PC Card still remain options.
Networking optionsJust as you would not expect to buy a desktop that lacked the ability to check e-mail and surf the Internet, the same is true of a mobile computer.
Wired: All new notebooks now include 56Kbps modem (RJ-11) and 10/100 Ethernet (RJ-45) connections. Some business-orientated notebooks might even feature Gigabit (10/100/1000) Ethernet.
Infrared: Some notebooks still feature an Infrared port, primarily as it's still used in engineering and business practice and consumers can also do things like connect their mobile phone to their notebook using it.
Bluetooth: A notebook with support for this short-range wireless networking standard comes into its own when used with Bluetooth devices like mobile phones, printers, headsets and PDAs.
Wi-Fi: Wireless networking is all the rage at the moment with certified public access points becoming more common and home wireless networking kits booming in popularity.
Both AMD and Intel machines can include wireless networking and often do - it's just up to the vendor, although Centrino notebooks have it built-in as standard. If you do choose to get Wi-Fi on your notebook or choose a Centrino model, just double check which Wi-Fi standards your notebook will support. Ideally, try to get a Wi-Fi module included that supports 802.11a, b and g standards.

Hard disk
If a computer's CPU is the brain of the PC, the hard drive serves as the heart, pumping vital data to the rest of the system. Providing long-term storage on your PC, the hard drive is the workhorse component of virtually every computer.
The hard drive rapidly records data as magnetic pulses on spinning metal platters - the more quickly a drive spins, the more quickly you can access and transfer data. In the mobile market, the overriding concern is power conservation. Slower-rotation drives can increase battery life but also reduce performance.
Hard disk speed is measured in revolutions per minute (rpm). The more your work or gaming requires access to the notebook's hard disk to load or save, the faster the disk you'll want. The range of hard disk options includes 4200rpm, 5400rpm and 7200rpm. It's also worth noting that hard disks are usually quite upgradeable with help from vendors.
Storage capacities for new drives grow every year, but the physical size (2.5in) of drives remains relatively constant. The biggest single notebook hard disk at the moment is 120GB and the minimum you should opt for is about 30GB.
If you are a multimedia user, and therefore most likely will be working with large file sizes, then you will probably want at least 40GB of hard drive space. The other option would be to use alternative (removable) methods of storing data, such as DVD writer.
Multimedia users who are interested in a desktop notebook may also be pleased to hear that such machines can sometimes support two hard disks in RAID (Redundant Array of Independent Disks) configuration which offers potential performance and data backup benefits.
Finally, more recent notebooks (such as second-generation Centrino models) also include a Serial ATA (SATA) hard disk interface. This is the connection type that the industry is moving to for newer SATA hard disks that are replacing the older IDE (EIDE) kind.

Memory (RAM)
Memory (RAM)
Whether they're inside a desktop PC or a notebook computer, RAM chips play the critical role of keeping the CPU efficiently fed with data or instructions from programs on the hard drive. How well the chips perform this role results in the difference between a CPU that misses computing cycles and moves like a steam locomotive and a CPU that speeds along like a bullet train.
There are three types of RAM available in notebooks: SDRAM (Synchronous Dynamic RAM) which is rarely used anymore on new notebooks in favour of DDR SDRAM (Double Date Rate SDRAM) and DDR2 SDRAM.
DDR SDRAM is now the default standard, even for value-orientated notebooks and overcomes the once-per-cycle handicap as it can send data to the CPU twice per clock cycle, for greater processing efficiency.
DDR2 (Double Data Rate 2) memory is a next-generation memory type used with the latest notebooks such as new Centrino models. DDR2 SDRAM offers a 60 per cent increase in peak memory bandwidth and power benefits over DDR SDRAM.
As with all computers, more memory is better. On all budgets, you should set 256MB as the absolute minimum, while 512MB or 1GB configurations are fast becoming the standard on many vendor-specified configurations. Currently most notebooks have the maximum RAM limit of around 2GB, but be sure to check as some less expensive models can max out at 1GB.
Upgrading the memory of your notebook is a great way to achieve better performance and more often than not, you can install it yourself! However, be sure to check if this voids your warranty first and also determine how many memory slots you have free so you can work out the combination of memory modules that's best for your machine and budget.

Although matters have improved dramatically in recent times, mobile graphics performance is one area where notebooks still lag behind desktop machines, and it's one of the most important aspects of a computer. It's the graphics controller that produces two- or three-dimensional images on the display.
As mentioned above, the graphics processor can be the difference between a 15in display providing a resolution of 1024x768 or much higher.
When you raise the resolution on your display, you add to the graphics board's workload by forcing it to produce a larger number of pixels. Likewise, when you increase the colour depth, it adds to the complexity of the work the graphics controller must perform.
All graphic controllers now easily manage the processing of 2-D images (such as those created when you browse the Internet, work in office applications or even watch a DVD. If this is all the graphics grunt you require from your notebook, then a less-costly, battery saving integrated graphics controller (that shares video with main RAM) should be fine. Examples include Intel's Graphic Media Accelerator 900 or its older Intel Extreme Graphics, ATI's Mobility Radeon Xpress or IGP series and also integrated graphics from SiS and even Trident.
Note: these "discreet" (dedicated) controllers are in virtually all instances integrated into your notebook's motherboard, although mainstream notebooks allowing graphics upgrades are around the corner.
However, if you want to play the latest 3-D games at a decent resolution and frame rate or you're a CAD designer, then you'll need a discreet graphics controller from ATI or NVIDIA with dedicated DDR video memory (up to 256MB).
The more powerful a graphics controller you require, the more expensive your notebook will become.
So if a discreet graphics controller is for you, your next step is to decide which brand and type will be most suitable.
Display
Display
The display is your window into your notebook computer's world and because it's your primary interface - it pays to get a good one!
Notebooks now all feature liquid crystal display (LCD) screens with Thin-Film Transistor (TFT) technology providing many advantages over monitors based on cathode ray tubes (CRTs), such as crisp text and no annoying flicker, which means they can help reduce eyestrain.
LCDs address each pixel individually, which means they can create sharper text than CRTs, but the high contrast of LCDs can cause problems when you want to display graphics. CRTs soften the edges of graphics as well as text, and although this can make it hard to read text at very small resolutions, it also means CRTs can blend and convey subtleties in images, for example, better than LCDs.
If you will be using your notebook as a desktop replacement for graphic-intense work, then perhaps you might consider buying a CRT monitor to connect to it when doing this sort of work. If this isn't an option, then choose a notebook with a large display, keeping in mind that a larger screen means a pricier and heavier notebook.
The screen sizes for notebooks (on average) range from 12.1in to the largest size of 17in (widescreen). A 15in display is the most common in notebooks today, followed closely by its 15.4in widescreen alternative.
Most notebook vendors are moving more and more towards widescreen only offerings for a variety of reasons including the native widescreen playback of DVDs and the fact that a widescreen's lower, wider profile is more durable against potential twists and knocks than a non-widescreen display/notebook lid.
In most cases, the larger the display, the higher the on-screen resolution will be, although this will usually depend on the type of graphics processor used. The graphics controller can be the difference between a 15in display providing a resolution up to 1024x768 or the more desirable maximum resolution of 1500x1400 pixels.
Some vendors (such as Dell), actually give you the choice of paying more for a better display panel that allows for a higher resolution. Keep this in mind. It's true that if you'll mainly be using your notebook for word processing, spreadsheets, and e-mail and Internet, etc, then screen size and resolution might not be important factors. However, keep in mind that a widescreen can be a good compromise between extra on-screen real estate and notebook weight.
Notebooks are also competing on brightness (measured in nits). Some vendors such as BenQ, Toshiba and Sony really pay attention to this area on selected models - and so should you when comparing specs!
A newer trend with notebooks (especially of multimedia-orientated models) is the use of a glossy, reflective coating over the display. Each vendor has a different name for their technology, but for the most part the results are the same: much improved contrast and colours instead of that washed out look. Sometimes this feature is standard, sometimes it's optional or not available. Be sure to ask about it - but remember that the downside can include you sometimes seeing your reflection at certain viewing angles (which can be distracting) and that any scratches can be more visible.
Another factor that distinguishes one notebook's display from another is its viewable angle. Quite often, less costly notebooks have lower quality screens that are not easily viewed from a side angle. When shopping online for a notebook, this is something you can't test. Here's something to try:
When you're at the notebook retailer: with the notebook on - and preferably playing a DVD movie, if the situation allows - stand in front of it and look at the screen. You should be able to see the display fine. Now take a step or so to the side until you're on about a 45 degree angle to the display. Can you still see the screen properly or is there an increase in darkness and loss of clarity? Now try standing about 10 degrees off the axis of the display and about 1m away.
Try this with a few notebooks and you should see the difference for yourself. This is more important if you are using your notebook to make presentations.

AMD Turion 64 Mobile Technology
AMD first launched its Turion processor brand in early 2005, explaining that it will give the Turion tag to its processors geared towards thin and light notebook computers because they use 35 watts or less of power.
The low-end MT-30 processor runs at 1.6GHz and features 1MB of Level2 cache, while the ML-37 also has a 1MB Level2 cache but runs at 2.0GHz.
Based on the same architecture as the Athlon 64, the Turion 64 is capable of running both 32-bit and 64-bit software.
Although the Turion 64 competes with Intel's Pentium M processor, AMD has not chosen to follow Intel's Centrino strategy, instead allowing notebook vendors to mix and match products they feel are best for cost or performance.
The Turion 64 is built using a 90-nanometre process, features AMD PowerNow! Power management technology, supports Windows enhanced virus protection and uses AMD's HyperTransport technology for FSB speeds up to 1600MHz (full duplex).

The Celeron M is quite an important processor as it's compatible with a variety of Intel's new and old notebook chipsets (915 Express, 910GML, 855x, 852x). This means you can still think about getting the latest notebook sizes and styles and save money by opting for this over a Pentium M processor. Just remember that you do lose a bit of performance (Celeron M processors have 1MB of level 2 cache - half that of Pentium Ms. Celeron M processors all have a 400MHz FSB and range from the 1.2GHz Celeron M processor 310 to the 1.6GHz Celeron M processor 383. As is the case with the Pentium M processor, there are also Ultra-Low Voltage versions available including the Intel Celeron M processor Ultra Low Voltage 383 which runs at 1GHz.
Intel Notebook Processors, Avoiding Centrino confusion
Intel Notebook Processors
Avoiding Centrino confusion
The majority of notebooks available today include Intel's Centrino technology. Centrino is Intel's name for its mobile computing platform that comprises three elements: a processor, an associated chipset and a wireless networking connection. Because Intel hasn't used a different logo or naming convention for the most recent Centrino updates, you need to make sure you find out which generation of the Centrino platform your potential notebook is equipped with.
The easiest way to do this is by looking at the chipset specifications. The first generation of Centrino uses the 855x chipset and the second generation (formerly codenamed Sonoma) uses the 915x chipset.
Only notebooks featuring these Intel's strict list of components get Intel's stamp of approval to carry the name "Centrino notebook". If just one component is missing or a competitor's product used instead, the notebook cannot be termed Centrino. Intel has created an architecture reference design to which notebook manufacturers must adhere (and have validated by Intel) if they wish to use the Centrino branding. It's important to remember that it's not like you couldn't wirelessly network a notebook before Centrino, Intel's marketing blitz as well as a surge in home broadband and networking just helped bring the idea of wireless to the masses. You can always get a Wi-Fi PC Card or Wi-Fi module to add wireless capabilities to a notebook without it built-in.
The second generation of Centrino, like the original, has three elements: the latest Intel Pentium M processors, a new 915 Express chipset and improved Intel wireless networking with support for the 802.11a, b or g standards.
The 915 Express chipset family: The 915 Express chipset (formerly codenamed Alviso) forms the centrepiece of 2005's Centrino update. The PCI Express (PCIe) bus architecture is said to deliver twice the input/output bandwidth of older notebooks - even more for graphics - and provides the exciting possibility of upgrading certain components in the future.
The chipset supports up to 2GB of dual-channel DDR2 (Double Data Rate 2) memory, a next-generation memory standard that clears the way for memory chips to run at faster speeds. The chipset also comes with support for a faster front-side bus (FSB), increasing the speed at which data flows between the processor and the memory from 400MHz to 533MHz for most configurations.
Other notable chipset features include support for up to eight USB 2.0 ports and the option for manufacturers to include a power-managed Serial ATA (SATA) hard disk interface.
Notebooks based on the 915GM chipset variant will use on-board graphics in the form of Intel's Graphic Media Accelerator 900. Although it's not for hardcore gamers, the 900 is twice the speed of the integrated graphic solution Intel offered previously and adds DirectX 9 support (required by the latest games), widescreen display and TV-output support. Manufacturers can also include Intel Hi Definition audio that supports DTS, THX and Dolby technologies for up to eight channels at 192kHz/32-bit quality. So the potential for home-theatre quality sound is definitely there.
Intel Pentium M processor: Some newer Pentium M (mobile) processors, formerly dubbed Dothan, were available in first-generation Centrino notebooks, but the range now spans the 2.13GHz Pentium M 770 down to the 1.5GHz Pentium M 705. A 90-nanometer manufacturing process is now used and 2MB of Level 2 cache included (double the original Pentium M) on the processor, along with support for the 533MHz FSB. Intel claims this can provide up to 33 per cent faster transfer rates than 400MHz FSB notebooks.
For ultra-slim and light notebooks or Tablet PCs, there are also low-voltage offerings such as the 1.5GHz Pentium M 758 processor or the Ultra-Low Voltage 1.2GHz Pentium M 753 - both with 400MHz FSBs.
In addition to improved SpeedStep technology that lowers or increases performance to prolong battery life, the new Pentium M processors also introduce support for Windows XP Service Pack 2's Executive Disable Bit function. This can help block malicious software from exploiting memory buffer overflow attacks.
Second-generation Wi-Fi: Notebook manufacturers now have the option to include 802.11a/b/g support thanks to Intel's new Intel PRO/Wireless 2915ABG network connection.
This new network connection supports many security standards including 802.11i - the highest level of enterprise encryption available today in addition to WPA2 and Cisco extensions 3.0. Finally, new software will make Wi-Fi easier to set up and manage at home or in the workplace.
The first-generation Centrino Pentium M processors utilise the Intel 855 chipset, which supports a 400MHz FSB, a 1MB Layer 2 cache, and the Intel PRO/Wireless 2100 wireless LAN chip. This wireless LAN chip enables easier connection to 802.11b, Wi-Fi certified access points, and reduces interference with other 802.11 signals as well as some Bluetooth devices. The first generation Centrino's 855GM chipset also includes integrated graphics based on Intel's Extreme Graphics 2 technology.
Unless you really tinker with power management options, battery life on the latest Centrino notebooks should be around the same as earlier Centrino notebooks, but with much better performance thanks to the features already outlined.

Intel versus AMD
The majority of notebooks you'll see advertised are likely to use Intel processors, primarily as part of Intel's Centrino platform, explained below. However, AMD is making inroads into the Australian notebook market, so expect to find an increasing number of notebooks featuring AMD Turion 64 Mobile Technology.
An AMD processor is still the only option if you're looking to run Windows XP Professional 64-bit Edition or a 64-bit Linux alternative. On that point, you may not have heard that the slated 2006 primary release of the next version of Windows (code named Vista) will be a 64-bit version, although a lesser-performing 32-bit version will be available for older machines.
Intel's next-generation of dual-core notebook processors (code named Yonah) is slated for release in early 2006 and will definitely be a performance boon. However, Intel has only confirmed 32-bit support, at least initially, so make sure you check the latest information if you're longing for 64-bit performance benefits.
All of the machines with Intel or AMD CPUs offer good performance, and all should run Microsoft Windows XP/Me/98/95 as well as other operating systems designed for x86 processors, including Linux. Always double-check though.
From this point, you can narrow your search further. The Celeron M processor and Mobile AMD Sempron processor are, respectively, Intel and AMD's entry-level processors for mobiles.
Portable performance notebooks on the other hand, will most often use Intel's Pentium M or AMD's Turion 64 processors.

All of the machines with Intel or AMD CPUs offer good performance, and all should run Microsoft Windows XP/Me/98/95 as well as other operating systems designed for x86 processors, including Linux. Always double-check though.
From this point, you can narrow your search further. The Celeron M processor and Mobile AMD Sempron processor are, respectively, Intel and AMD's entry-level processors for mobiles.
Portable performance notebooks on the other hand, will most often use Intel's Pentium M or AMD's Turion 64 processors.
Performance impacting CPU technologies
Micron technology: The size of the transistor technology on the CPU. Smaller means the processor can run more quickly and will generate less heat.
System bus/Front-side bus (FSB) speed: This is the channel through which the processor accesses the main memory. The faster this is, the more quickly information can be pulled from memory.
Secondary (Level 2) cache: Secondary cache is a small amount of memory (generally ranging from 128KB to 2MB on notebook processors) that is on the actual CPU. The memory, while small, is accessible at very high speed and reduces the need for the processor to access the main memory, which is done via the slower system bus.
Voltage: Cutting the voltage (and therefore the speed of the processor) helps reduce power consumption as well as heat generation, which is a significant factor in cramped notebook cases.
Power management: Some technologies modify the physical power consumption of the CPU based on operational requirements. Techniques include reducing the clock speed or implementing variable voltages. This reduction of power consumption provides longer mains-free operation.

Processor and chipset
When purchasing any personal computer, one of the fundamental factors to consider is the central processing unit (CPU). In a notebook computer this is even more important, as the CPU is not only the brains of the machine, it is one of the factors in determining how long the notebook will operate while disconnected from the mains power and running on the battery.
The processor must be able to deliver the performance you require while not draining the battery too fast. Of course, processor vendors are not charities, and the more value they put into the CPU - speed, power reduction, smaller packaging for super-portable notebooks, and so on - the higher the price tag of the processor and, correspondingly, the overall price of the notebook.
Which notebook you buy, and which processor it includes, will in most cases depend on your budget. Within the AMD and Intel mobile processor range there is a wide variety of individual CPUs.
It's important to know that just because processors are marketed under the same brand, such as Pentium M or Athlon XP-M, it does not mean that they are all identical apart from clock speed. For example, processors in the same range can differ in micron technology used, the amount of Level 2 cache, and clock speed. Within processor brands, differences exist in the underlying silicon gate technology (eg, 0.13-micron or 90-nanometer). Generally, the smaller the build process is, the newer the technology.
Other differences include the power consumption figures, the power management technologies included, and the amount of secondary (Level 2) cache on the processor. All these factors affect CPU performance, which is why Intel and AMD have both moved away from using just the gigahertz (GHz) speed to identify a processor and instead have started using numbering systems that they feel better label their products.

Ruggedised portables
Ruggedised portables
Popular with on-site engineers, law enforcement and other field-staff, ruggedised portable computing devices continue to gain a niche following.
There are special ruggedised alternatives of standard notebooks, tablet PCs and even PDAs available from a variety of vendors, but in Australia, Panasonic's ToughBook range continues to lead the way.
Ruggedised notebooks are not to be confused with standard, well-built notebooks that feature magnesium alloy casing, splash/water-resistant keyboards and shock-mounted hard disks: ruggedised notebooks can feature drop and sometimes-bullet proof casing, dust protected sealed connector covers, extra security and more. The downside is that such extra features usually cost quite a bit more and the specifications of the machines are usually a little behind the curve.

Palm/hand top computers
What do you get when you cross a PDA with a notebook or Tablet PC? Answer: handheld computers of an in-between size that have no problems running Windows XP and are usually equipped with a built-in hard disk, Wi-Fi, USB functionality and sometimes, touch screens.
Although handheld portable computers are yet to really arrive in Australia with any force, there are a few different brands available overseas. These include Sony's U-series, the FlipStart PC and the OQO model 01.

Tablet PCs
Tablet PCs
Tablet PCs are just like a normal notebook but with a twist. There are two types of tablet PCs: the first are convertible models that can also function just like a normal (or "clamshell") notebook, complete with keyboard and cursor control pads/sticks. Alternatively, there are also dedicated tablet devices.
Both types of tablet PCs feature touch-screens (designed for use with a bundled stylus) that can be rotated between portrait and landscape views. Until the next generation of Windows (now codenamed Vista - formerly Longhorn) ships, Tablet PCs will use the Tablet PC edition of Windows XP that has been specially tweaked to include handwriting and speech recognition features.
Tablet PCs have a roughly $300-$500 premium over a similarly specified standard notebook and as such as still a very niche product suited best to certain areas of business and design.
Most of the big name vendors such as Lenovo (which now markets the ThinkPad range after the acquisition by the Lenovo Group of the IBM Personal Computing Division), HP/Compaq, Fujitsu, Acer and Toshiba in addition to some lesser known-brands offer tablet PC models.
There are also wireless "tablet" displays that include a built-in processor, but they're not a computer! They need to connect to a PC or the Internet over Wi-Fi to browse content. Nokia's recent 770 Internet tablet and ViewSonic Airsync range are two such examples.

Sub-notebooks
You may also come across a category of notebook called sub-notebooks. Around the 1.5kg-and-less mark, they come with a screen of small-to-medium size, and generally great performance. However, the price tag isn't always as lightweight. With sub-notebooks, most things (such as an external DVD writer) that aren't absolutely essential to the machine's operation can usually be detached and left at home or in the office, giving you the choice between functionality and portability.
Of course, some sub-notebooks are created more portable than others. Consider whether you want to sacrifice an extra 300g or 400g in favour of a larger screen or more ports and connectors. Also, check that you aren't giving up too much in exchange for portability, as the smaller keys on some sub-notebooks can make them difficult to use. Toshiba's Portege R100 and revamped Libretto U100 machines are perfect examples, as are Sony's T-series Vaio machines and Fujitsu's P-series offerings.

How much do I need to spend?
How much do I need to spend?
How much you need to spend depends on what you will be using your notebook for. If you only want to access your e-mail, browse the Web and do word processing, then you can get away with spending between $1500 and $2000 for a new machine (even less if you get an older and or second-hand model).
If you are a medium-level user, using your notebook to play games or to work with multimedia applications, then you will want to spend more on a powerful processor and graphics controller, more storage space, and a bigger screen. For this type of use, you'll be looking at around the $2000-$2500 and up price-range.
Remember that the more features your notebook has, the more expensive it will be. If you opt for a DVD-writer drive instead of DVD-ROM, want increased hard drive capacity (say, over 40GB), a screen size more than the standard 15in, wireless capabilities and a more powerful processor, then the price of your notebook will increase accordingly. The trick is to figure out which configuration you will need.
Buying a notebook with the latest processor or graphics controller is not necessary if you will only be using it for word processing and Web browsing, and have no plans to extend your usage.
Most users will fall in the $2500-$4000 category, with only high-end corporate users, content-creators and avid-gamers looking at spending over $4000.

What will I be using the notebook for?
If you won't be travelling frequently with your notebook, then battery life and weight will not be a primary concern. Instead, you may want to concentrate on ramping up the processor, screen size and memory. If, however, you will be carting your notebook around with you on a regular basis - travelling interstate or overseas, around a university, or perhaps you frequently work away from the office - the size and weight of your notebook, and its battery life, become more important.
You may prefer to scrimp on the size of the display to lighten the load, so opt for a 12-14in instead of 15-15.4in or 17in widescreen varieties. If, however, the graphics capabilities and size of the screen are important, this may not be the best option. If you don't play games, edit video or watch DVD movies, there's little point buying a model with the latest mobile graphics card because a built-in chip (integrated graphics) should meet your needs.
Also, there's nothing to say that you have to buy a model with everything you want already included. Consider buying a basic unit and adding to it. It could work out a lot cheaper to obtain things such an external TV card and DVD writer when the need arises.
If you only want a notebook to store such things as contacts, and occasionally enter small amounts of data, a PDA (personal digital assistant) may be more suitable to your needs. These devices are reliable, run for days or even weeks on a single charge, and can be carried more or less anywhere. PalmOne's 4GB LifeDrive PDA is a recent perfect example..

How important is mobility?
The degree of mobility of your notebook is a combination of size, weight and battery life. You will need to consider how often you will be carrying it around and if you will mainly be relying on the notebook's battery or an external power source. Notebooks generally weigh around 3-4kg, but they can weigh as little as 1.5kg and as much as 6kg, depending on the model and features included.
A lighter notebook may not have an internal CD/DVD drive or floppy disk drive, may have a smaller screen, or reduced storage capabilities. Alternatively, the larger (and much heavier) desktop-replacement machines usually have worse battery life because of their big power-draining screens and components. However, they can feature all the trimmings such as multiple CD/DVD drives and hard disks, cutting-edge mobile graphics, widescreen displays up to 17in and full-sized keyboards, complete with dedicated number pads.
Most notebooks in PC World's Best Buys weigh around 3kg, with some hovering around the 2kg or less mark. These particular weights are for the notebook itself, not including the power supply or often-used accessories such as external drives. However, the Best Buys do also list the combined weight of such accessories to help you determine the total weight you will be carrying around in the bag.
Notebooks now mostly use Lithium Ion (Li-Ion) batteries that operate for one to three hours on a single battery charge. However, if you use all of the power saving options available, and depending on the number of cells in the battery (the more cells, the longer it lasts), a Li-Ion battery can last up to six or seven hours.

Desktop PC or notebook?
Is a notebook the computer for you or are you more suited to a desktop system? If you want a notebook as a desktop replacement, you must be sure of your needs: if you think you will want to upgrade in the near future, or work with a larger monitor, then a desktop system would generally be preferable.
To increase your productivity, you can easily use your notebook in conjunction with a second monitor as nearly all notebooks now come with a VGA-out port and in some cases, even a DVI-I port for connection to LCD monitors without an adapter. Some notebooks are still equipped with a PS/2 port for an external mouse and or keyboard but most now feature at least two high-speed USB 2.0 ports allowing expandability options for printers, mice, joysticks, and other peripherals.
FireWire ports (used to connect items such as digital video cameras and external hard disks and) are also becoming more common, especially in notebooks geared towards multimedia use.
What the decision really boils down to, though, is whether you need your computer to be mobile. For the medium term to come at least, desktop PCs will remain cheaper than notebooks at similar performance levels and provide better value while being easier to upgrade.

Notebook systems have grown in popularity due to their increasing performance and portability. Many systems are even now being marketed as replacements for desktop systems, but few can perform at the same level as a desktop system particularly when it comes to graphics. This guide will help you to look at some of the key items you want to look at before you purchase your next PC notebook system.
Size and Weight
Obviously the size and weight of a notebook is important. Ultraportables offer light weight and sizes but sacrifice items such as drives. Desktop replacements have equivalent power to desktop systems, but they are heavy and bulky making them difficult to carry around. When shopping for a laptop, make sure to pick up the systems and verify its something you are willing to carry. Don't forget to also consider the weight of accessories such as AC adapter when carrying around the notebook.
Understanding Notebook Size/Weight
Processors (CPU)
Notebook processors typically were slower than desktop CPUs, but that has changed. Dual-core processors are starting to become common and help with multitasking. The type of processors found in the notebook will vary based upon the size and purpose of the notebook. They have a direct impact on performance as well as battery life so comparison can be difficult. Check out my listings for suggested processors for the various types of notebook PCs available.
Understanding Notebook PCs
Memory (RAM)
Notebooks are generally more restricted in the amount of memory they can have compared to desktops. When looking at computers you want to make sure to check out the maximum memory the system can handle as well as the amount that is installed in the computer. It's also useful to find out if a memory upgrade can be done yourself or if it has to be done by a technician. 512MB should really be the minimum amount of memory to consider with at least 1GB for improved performance.
Understanding Notebook Memory
Displays and Video
The video on a notebook computer is comprised of the display and the video processor. The display is comprised of the screen size and the native resolution. The larger the display, the higher the resolution will typically be, but it also will impact how portable the system is. Wide screen displays are also becoming more popular. The graphics processor will determine the performance of the computer in things such as 3D graphics and PC gaming.
Understanding Notebook Video
Drives
How much storage space will you need? Hard drives are fairly straight forward in terms of the size and the performance may be impacted by the rotational speed. Optical drives play a more important role when purchasing a notebook PC. These can either be fairly simple CD-ROM drives for installing software all the way up to the latest high definition DVD burners. In most cases, it is best to at least get a drive that is capable or reading DVDs and burning CDs or DVDs.
Understanding Notebook Drives
Networking
The ability to connect to the net is integral to most notebooks today. Look for systems that include a built in 56Kbps modem and Fast Ethernet. With the rise of wireless networking, this is also found in most new notebooks. For the minimum amount of wireless connectivity, look at getting a notebook with 802.11b/g. Systems with an 802.11a/b/g will give you the most amount of connectivity.
Understanding Notebook Networking
What is Networking?
Battery Life
How good is a portable computer going to be if you are only able to get 30 minutes of computing time on a single charge? Try to find the manufacturer’s listed battery life for the standard battery. Look to get a system with at least 2 hours of battery life under normal conditions. If you need extended time unplugged, look for laptops with media bays that can double as extra battery slots or have extended life batteries that can be purchased.
Warranty Plans
Laptops take a lot of abuse and are more prone to breakdowns due to their portability. When buying a system, make sure to get at least a 1 year warranty from the manufacturer. If you will be using the system heavily, a system that comes with a 3 year warranty might be a better choice but it will cost more. Third party extended plans are not a good choice unless service is done through the manufacturer.

Gateway E-475M
CNET editors' review
Reviewed by: Dan AckermanEdited by: Matthew ElliottReviewed on 5/9/07 Release date: 5/9/07
Intel has generated plenty of buzz by revising its popular Centrino platform with a new set of specs that promise better performance, better battery life, and better Wi-Fi connectivity. You can identify these new systems by the new Centrino stickers, (Centrino Pro for added IT manageability, Centrino Duo for everyone else). One of the very first laptops based on this new platform--developed under the codename Santa Rosa--to come our way is the Gateway E-475M, a mainstream Centrino Duo 15-inch model aimed at business users that has enough style for home users as well. The E-475M boasts plenty of business-friendly security features, including a fingerprint reader and a smart card slot. Priced upward of $2,000, this is an expensive system, but knocking down components and stripping away extras including 802.11n Wi-Fi and a fancy port replicator can shave almost $700 off the price, making this a flexible system for those who need a laptop that works in both the home and office.

The Gateway E-475M sits firmly in the mainstream category of laptops: big enough to work comfortably on for long stretches but small enough to carry around occasionally without much hassle. It's about a half-pound heavier than similar business-minded 15-inch laptops, such as the Toshiba Tecra A8, but feels slightly unbalanced, with most of the weight at the rear of the system where the battery sits.
If you're looking for something slightly more compact, the E-475M has a sister system, the 14.1-inch E-265m. It comes in a little lighter, around 6 pounds, and packs almost the same components into a smaller package, although at the expense of screen size and resolution.
The Gateway E-475M's basic, matte-black finish is attractive, if not exciting, and the pieces inside of the system--including the keyboard, the tray, the screen bezel, and the touch pad--all match, giving the E-475M a uniform black look. The touch pad has a separate scroll zone, which we always like, and the single quick-launch key brings up the Windows Vista Mobility Center menu by default. Maybe we're spoiled, but a few extra quick-launch keys would be welcome, even on a business-minded system.
One interesting point: Our review unit came equipped with both a trackpoint and a touch pad, but the trackpoint has been removed from the final shipping version of the E-475M. While the trackpoint has dedicated fans, we won't miss it.
The 15.4-inch wide-screen LCD display offers a 1,680x1,050 native resolution, which is better than the 1,280x800 resolution more commonly found on a screen this size. After seeing so many systems with media-friendly, glossy screen coatings, it was refreshing to find a good, old-fashioned matte screen that was easy to see even under the glare of our desk lamp.

As the above chart illustrates, the ports and connections are in line with what we'd expect to see on a mainstream business laptop, plus it adds a media card reader, which some business-oriented configurations leave out. We were pleased to see the inclusion of faster Draft N (802.11n) Wi-Fi technology, which we expect to see in many new laptops from this point on. Bear in mind, you'll need a 802.11n router to make use of the faster connection.
Our preproduction unit included a host of upgrade options--a high-end CPU, the 802.11n Wi-Fi chip, 2GB of RAM, a 256MB ATI Mobility Radeon X2300 graphics chip, and a port replicator with a DVI output and a slot for recharging an additional battery--to drive the price up almost $700 above the $1,399 base. We won't know exactly what your options for knocking the price down are until Gateway officially launches the system on May 9, but we do know the port replicator is a brand-new model that added $179 to our configuration.
Intel claims that Santa Rosa, with its new 800MHz front-side bus CPUs and Turbo Memory (extra flash memory built into the motherboard to speed up access times), will give systems a boost. Testing three Santa Rosa systems with the new 2.2GHz Intel Core Duo T7500, we saw nearly identical scores on CNET Labs' Multimedia multitasking test from the Gateway E-475M, the Gateway E-265M, and the Lenovo ThinkPad R61. They were faster than a similarly configured non-Santa-Rosa system, the Dell Inspiron E1505, and even edged out one of the few laptops we've seen with a high-end T7600 CPU, the Alienware Area-51 m5790 Special Edition. The differences were minor to be sure, but as we test more new Centrino Pro and Centrino Duo systems, we'll get a better picture of the performance gains to be found with the Santa Rosa platform. For now, we think that while it's not a huge leap forward, the fact that this system is one of our top performers is a good sign. In anecdotal testing, the system certainly felt powerful, even while multitasking, but we'd expect nothing less from any recent laptop.
Despite the impressive application performance, neither the Gateway E-475M nor the other early Santa Rosa systems we've seen are suitable for serious gaming. Instead of integrated Intel 965 graphics in the new Santa Rosa standard, our E-475M review unit featured an ATI Mobility Radeon HD2300 with 256MB of dedicated video RAM. The system was too slow, however, to run our standard gaming benchmark tests at our bare minimum acceptable frame rate of 30 frames per second, but in anecdotal testing, we were able to get a playable, if not always smooth, frame rate on the upcoming Vista-only game Halo 2 by knocking the resolution all the way down to 800x600.
The Gateway E-475M ran for 2 hours, 37 minutes on our DVD battery drain test, using the included six-cell battery. Our DVD battery drain test is especially grueling, so you can expect longer life during casual Web surfing and office use. One of the major selling points of Santa Rosa is improved battery life, through more efficient CPUs and smart throttling of the CPU and front-side bus. The E-475M had impressive battery life, and beat other 15-inch non-Santa Rosa systems, such as the Toshiba Satellite A135-S4467 and the Systemax Pursuit 4155, by more than 30 minutes. While it's not a game changer, none of the Santa Rosa laptops we've tested to date have lasted less than two hours.
Gateway backs the system with a three-year mail-in warranty. A variety of upgrades are available, including next-business-day on-site service for only $30. Upgrading to a three-year plan with accidental damage protection, however, costs $199 more than the default warranty. Gateway offers 24-7 toll-free technical support, and the company's support Web site includes the expected driver downloads and FAQs, as well as the capability to send e-mail to or chat live with a technician.

First Intel Santa Rosa systems reviewed
The systems here represent some of the very first laptops featuring Intel's revamped Centrino platform, code-named Santa Rosa.
While marketing jargon comes and goes, Centrino is one bit of clever stickerware that's scored big with the public. Laptops bearing the Centrino sticker (introduced in 2003) basically feature a specified combination of processor, chipset, and wireless-network interface, promising a seamless online experience and a better battery life. You can identify Santa Rosa systems by their new Centrino stickers: Centrino Pro for added IT manageability, and Centrino Duo for everyone else.
What do the new Centrino Duo and Pro platforms offer to you, the laptop-buying public? To summarize, the new Centrino includes a handful of new Core 2 Duo processors with clock speeds as high as 2.4GHz; a new motherboard chipset with a faster 800MHz front-side bus and an optional dedicated memory cache; a new integrated graphics chip with a larger allocation of memory; and a new wireless card with support for Draft-N wireless. (For more detail on each of these items, we direct you to this Centrino review on Crave.)
The nearly identical Gateway systems (the 14-inch E-265M and 15-inch E-475M), and the 14-inch Lenovo ThinkPad R61 are a little dry, aimed squarely at business users (although the Gateways are stylish enough to pull double duty in the home). In contrast, the HP dv9500t is designed for fun, with a giant 17-inch display and plenty of consumer-friendly extras for that portable, home theater experience.
Our initial testing of these systems showed modest gains in performance and battery life over similar non-Santa Rosa models. For now, we think that while the new Centrino platform is not a huge leap forward, it's good enough to quickly become the default choice for many consumers. As we test more new Centrino Pro and Centrino Duo systems, we'll get a better picture of the performance advantages to be found in the Santa Rosa platform.

As we test more new Centrino Pro and Centrino Duo systems, we'll get a better picture of the performance advantages to be found in the Santa Rosa platform.
Centrino Duo (aka Santa Rosa) explained
Today's platform announcement from Intel may have left you scratching your head, and rightly so. After all, the company is replacing its Centrino Duo platform with a whole new platform called...Centrino Duo. And then there's Centrino Pro. Both of which, up until this morning, were called Santa Rosa (and will probably still be referred to by that moniker for the next few months). Confused yet?
Fortunately, we've had some time to wade through the marketing buzz and technical specs to figure out the whole story. Boiled down, it's this: the new Centrino Duo platform includes a handful of new Core 2 Duo processors; a new chipset with a faster front-side bus and an optional dedicated memory cache; a new graphics solution with a larger allocation of memory; and a new wireless card with support for Draft-N wireless.
Centrino Pro, meanwhile, has all those new features, plus additional remote management technologies designed for businesses. Essentially a mobile version of the vPro technology found on desktops, the Centrino Pro enhancements let IT managers upload configuration changes to a PC over a network. Centrino Pro also allows for asset management and remote diagnostics independent of the laptop's operating system, meaning the machine doesn't have to be on for IT workers to access it.
As with every iteration of notebook technology, all this is supposed to add up to better performance and longer battery life (which, thus far, it more or less has--see our first few reviews of Santa Rosa systems). While the changes aren't revolutionary, we do think they're worth seeking out if you're already in the market for a new laptop. After the page break you'll find our rundown of all the new Centrino features and what they mean to you.
New processors. The processors are a small part of this platform launch, built as they are on the same architecture as the previous generation. But they all now support the new 800MHz bus (see below), and Intel has upped the maximum available clock speed to 2.4GHz. Also, given that Intel is using the same name for this platform as the previous version, the processor number is going to be the easiest way to determine whether the laptop you're buying has the new or the old Centrino Duo. The new processors and pricing are as follows:
Intel Core 2 Duo T7700 (2.4GHz): $530
Intel Core 2 Duo T7500 (2.2GHz): $316
Intel Core 2 Duo T7300 (2.0GHz): $241
Intel Core 2 Duo T7100 (1.8GHz): $209
Intel Core 2 Duo L7500 (1.6GHz): $316
Intel Core 2 Duo L7300 (1.4GHz): $284
Faster overall performance--eventually. The new chipset increases the frequency of the front-side bus to 800MHz, which should theoretically help all the components of the system communicate more quickly. But in order to realize the full potential of the FSB, every component has to be rated at the higher speed--and 800MHz RAM won't hit the market until later this year. Nevertheless, if our first few Centrino Duo systems are any indication, you can expect to see modest gains in performance over the previous generation even with existing 667MHz memory.
Better--and hungrier--integrated graphics. The new Intel GMA X3100 integrated graphics now offer DirectX 10 support and have a higher allocation of VRAM--up to 384MB. That bump will help Vista's graphical interface run more smoothly but also means that more of your system RAM can be gobbled up by graphics. You'll likely want to stack your laptop with more than the standard 1GB of RAM just to keep the whole system running smoothly.
Longer battery life. The new chipset includes a number of features designed to lower power usage and extend battery life. Dynamic front-side bus switching lets the system drop into a "low-frequency mode" to conserve energy, while an Enhanced Deep Sleep mode is designed to use less power when the system is idle. Our initial tests of laptops built on the new platform have shown modest gains in battery life over previous-generation Intel systems.
Theoretically faster boot and load times. The new Intel Turbo Memory (codenamed Robson), available as an option on Centrino Duo and Centrino Pro systems, is flash memory that's incorporated into the motherboard. The Turbo Memory stores a cache of commonly accessed information, such as the operating system and software, so you can boot the computer or launch applications without spinning the hard drive. While our initial anecdotal tests revealed no difference in start times, Intel claims the Turbo Memory can shorten boot times by as much as 20 percent.
Faster wireless. Many people (cough) thought Santa Rosa would include support for 3G and WiMax connections. But the only enhancements to wireless on the new Centrino Duo and Centrino Pro notebooks is support for 802.11n networking. Of course, taking advantage of the faster speeds and better range of 802.11n will require you to purchase a Draft N router--a tricky proposition, considering the official 802.11n spec has yet to be finalized.
Overall, we'd say none of the above technologies is revolutionary, but each has the potential to bring incremental gains in performance and battery life--a step in the right direction, especially considering Vista's reputation as a resource hog. Again, we wouldn't recommend rushing out immediately to buy a Centrino Duo system, but if you're in the market for a new laptop, the new platform will give you a modest boost now while letting you adopt faster memory and wireless speeds as they become widely available.
