Impressive technology, but increasing cores doesn’t necessarily increase performance.

There is only one card in this picture. No, really. Okay, let’s discuss this.

Quad-core makes it powerful and good value at the price. Noise and stability suffer though.

Slim and stylish, this isn’t the most powerful quad core we’ve seen, but it’s by far the cheapest.

A fast, quiet, good-looking PC that's great value.

Big, brash and versatile, but for top-end PCs only. Enthusiasts will love it.

Fantastic hardware. The GPS software is mediocre, but you can buy your own.

Plenty of modern phones support email, of course, but what always made BlackBerry special was its push technology. With this, you don't need to dial up to collect your email: just sit back and wait for the messages to come to you. Wherever you are, if an urgent email comes through to any of your email addresses -- and the 7100v supports up to 10 -- you can act on it instantly.

Revolutionary features and stunning power: for anyone lucky enough to have the cash, the Lenovo ThinkPad W700ds is the ultimate mobile workstation

Fantastic design and highly-configurable power make this XPS useful, desirable and good value.

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

There’s so much to like about this package that it might just be worth switching operating systems to get hold of it.

A feast of features for those willing to pay

Palm has embraced Microsoft, creating a neat 3G business phone in the process.

A great piece of hardware, backed up by BlackBerry’s legendary services.

Big and heavy but the features this 3G phone sports are phenomenal.

Dell’s first foray into using AMD processors is a modest performer, but fair value.

While Intel is rolling out new designs, AMD's focus is on getting the most out of its existing Phenom II process. The AMD Phenom II X4 965 Black edition is just what the doctor ordered.

A fine combination of remote management, all-round fault tolerance and top build quality

Not the most useable email tool, but very sleek.
