What is it? Another handheld computer.

What's so special about it? Good for travelling because it's very small: 4.8 inches by 3 inches by 0.7 inches.

All palmtops are small. That's very true - but this has a slot in the back where you can plug in expansion modules.

Like a Gameboy? That's right. Plug in a tiny modem and connect to the Internet via a mobile phone. There'll soon even be a Global Positioning Device that shows you where you are on a map.

I just want simpler stuff. Plug in a Tiger Woods golf game, then. Or a module that turns it into a basic digital camera. Soon there'll be an MP3-player module.

And without the modules? It's an organiser, diary, memo pad and calculator. The standard versions have 2MB of memory, the Deluxe has 8MB.

What else? Connect it to your PC via a special cradle or infra-red port. And there's a travel feature called City Time: the hour in every city, plus a shaded map showing where it's night.

Who makes it? Handspring - founded in California two years ago by people who earlier designed Palm computers.

What do they cost? Three models at £116, £149 and £199. Then there's the modules: about £100 for the modem or the digital camera, £55 for an 8MB extra memory module, £25 for Tiger Woods.

Where do I buy it? Electronic shops, including Dixons and Carphone Warehouse; on the net from www.handspring.com/uk or www.zircon.com; mail order from Microwarehouse (tel: 01928 579000).

Do say: It's got WAP/WEB, e-mail and SMS management.

Don't say: What's wrong with a notebook and pencil?
