The Hi-Grade Xperian can simply be described as a bundle of essential technology ingeniously put together in one desirable package.

A standard-issue corporate laptop with suspect ergonomics.

Looking sleek and a little smaller than your average midi tower, the t134a sits on top of the Pavilion series. This machine is a powerful home/office PC – not rigged purely for gaming.

The D400S packs the usual gear, and offers well-thought out front-mounted FireWire along with 802.11b on/off controls for the optional WLAN device. We were surprised the right-hand side of the chassis contained absolutely no connectivity options – a shame given the inclusion of only a single PCMCIA port. Three USB ports are present – two rear-mounted and one on the left-hand side.

To test the TFTs in this month's Labs we relied on a few different methodologies. All TFTs were tested on the same test bench PC consisting of a Gigabyte 8GE667-PRO motherboard and 2.53GHz Intel Pentium 4 processor with 512MB of DDR RAM, running Microsoft Windows XP Professional.

Apple has outed a "mightier" Mac Mini, boasting the same compact shell but with boosted memory, bigger hard drives and a speedier processor

Incredibly powerful laptop system, with a few small issues that hold it back from true glory.

A stunning screen, generous specification and good performance combine with superb results for the Dell XPS 16

Incredibly powerful laptop system at high spec, but you can also opt for a cheaper, lower spec version

If you’re locked into Intel, there’s value to be had. But AMD’s Sempron is the budget-buyer’s king.

We help you determine whether your current PC can run Vista and which version of the operating system best suits your needs.

Swiping the hardware from the PC Authority test bench, we went about putting together our Shuttle XPC. Immediately we were confronted by one of the idiosyncrasies of small form factor PCs: squeezing all the hardware in the tiny space inside.

Core i7 for laptops looks set to change the face of portable computing forever

Looks and feels great, but a hefty price – once you’ve tweaked its specs – means that rivals offer better value

You’ll see a lot of hype surrounding the 3.06GHz Pentium 4, and doubtless you’ll see benchmark scores for the new processor. If you do, regard them with a heavy degree of skepticism because all is not rosy with this chip.

The Athlon XP 2700+ represents a significant leap forward for the Athlon line – it solves a long-term problem by stepping up the default frontside bus (FSB) speed from 266MHz to 333MHz.

The Athlon XP 2700+ represents a significant leap forward for the Athlon line – it solves a long-term problem by stepping up the default frontside bus (FSB) speed from 266MHz to 333MHz. This means that the Athlon XP can finally run in sync with 333MHz DDR RAM. While most currently available Athlon motherboards support 333MHz DDR, there is virtually no performance boost between this and 266MHz DDR when running an Athlon XP with a 266MHz FSB. The extra speed offered by the RAM quite simply goes to waste, because the CPU can't keep up with it.

Dell's previous 13.3in XPS - the M1330 - was a delightful portable, but the XPS 13 makes it look scruffy by comparison.
