Sony never lets you forget that it creates Personal Entertainment Organisers; Personal Data Assistants simply aren't trendy enough. But if you ignore the marketing, it rapidly becomes clear that the TJ35 is going head-to-head with the supposedly business-oriented Palm Tungsten E (January 2004, cover CD).

It's been a long time between Palm releases, but the Tungsten T makes the wait worthwhile.

A hugely likeable phone that excels at web browsing and manages to just live up to its ambitious name.

The Zire 71 isn't a business tool. It's not even a straight forward personal organiser. Palm is targeting the ears of Sony's CLIÉ range, the new PDA boasts not only a headphone jack for MP3 player use, but also a 640 x 480 camera. The camera is ingeniously hidden behind the metal backplate. To activate, you simply slide down the backplate to reveal the lens, the screen becoming a viewfinder. You can save photos to the memory – 12.7MB before you start loading programs – or to an SD/MMC card that slips into the top-mounted slot.

Dell has waited several years to release its own PDA, and now committed to Pocket PC, Dell's main weapon is aggressive pricing that's on the verge of insane.

Still not sure whether it's worth upgrading to Vista? We put XP and Vista through the ultimate face-off.
