What is it?
It's a PDA with a built-in mobile phone.
What does it do?
The organiser part uses the Palm operating system to manage your diary and contacts. The phone is a dual-band GSM that will work in Europe but not in the US. Putting them in the same box allows the Treo to offer full e-mail and internet access on the move. Not bad for a svelte 153g. Although tiny, the keyboard is better than the buttons on a mobile, but expect web access to be very slow until GPRS compatibility comes later in the year.
What's the competition?
BT Cellnet's Blackberry is better for e-mail, thanks to its always-on GPRS connection, but it doesn't have a phone. The Nokia Communicator handles faxes and e-mail attachments, but looks like a brick and weighs almost as much. Nothing else out there squeezes so much into such a small package.
Where can I get it?
It's out this month, priced at pounds 399, excluding connection and call charges.
