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

Performance per watt has taken a backward step, but it’s very fast with the right apps.

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.

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.

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

An interesting concept But performance is determined by drivers and ultimately it smacks of gimmick.

A versatile single-socket rack server with a wide range of processor choices, plus a good warranty for the price.

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.

When we first reviewed the hw6515, we were bowled over by how much HP has managed to cram into such a small device.

The XDA (January 2003, page 41) and the XDA II have both done well in PC Authority reviews before, but our main complaint has been one of size: the XDA's are normal PDAs, but big phones. The XDA IIs still keeps a large touchscreen, but the unit is slightly slimmer and thinner than the previous models.

The key differentiator with the PDA2k over other PDAs is the whopping 128MB of RAM in-built for media and files. On top of this there's a separate 64MB ROM for the OS and an SD/MMC slot for further expansion.

The latest iteration of the Pentium 4, code named Prescott, is an interesting development for a few reasons. First off, it represents Intel's entry to the world of 90nm (90 nanometre, or 0.09 micron) fabrication for processors. For the uninitiated, all this means is the size of individual components on the processor core have been shrunk to even smaller levels. It's a natural part of processor evolution to shrink the size of components, as it allows more transistors to be packed into a smaller space, reduces heat and resistance, and this all leads to faster CPUs.

Chance or coincidence? AMD releases the Athlon 64, specifically targeted at the consumer performance market, and only days later Intel announces a secret processor aimed squarely at the same MHz-hungry community: the Pentium 4 Extreme Edition (P4EE).

Quick-release hard disks can’t make up for design flaws.
