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

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).

This rather optimistic time assumes no use of the backlight, but we found half-brightness to offer the best compromise – and even at this setting, the V35's screen impresses.

If there was a PDA king, this would be it. HP includes everything in the iPAQ H5550 including 802.11b, Bluetooth and fingerprint recognition. Most importantly, this is the first PDA we've seen to run Pocket PC 2003

The Toshiba e740 (review on the PC Authority Web site) boasted great features such as Type II CF and SD/MMC card slots, and the optional expansion pack which includes a VGA output and USB port, allowing the connection of a keyboard and a projector. The e750 goes two steps further. You can now send 16-bit colour to a projector at a resolution of 800 x 600, and this WiFi version connects wirelessly to a suitably equipped Toshiba projector. Another WiFi enhancement is support for Voice-over-IP with an enhanced microphone socket so a microphone headset can be used.

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.

Never judge a book by its cover, they say, and nowhere does this apply better than to the Nokia 9210i Communicator.

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.
