This revolutionary little machine is a great choice for kids at school, or travellers looking for a basic unit to update their blog, check e-mails or write their travel diary with. We wouldn't recommend it as much to the elderly, simply due to the keyboard and screen size, but it is simple to use and does the job well.

It's small, affordable and easy to use. Business users will appreciate the fast networking options and the ExpressCard slot. Travellers and students will love its large hard drive capacity and the fact that it's compact but still easy to use.

For its size and price this Acer is a great purchase. It has a strong selection of connectivity options crammed into a small package and good battery life as well.

Physically, it's the same as the Linux version, and it has less storage space, but it does feel a little faster and it's much better suited to playing videos.

Even if you've never used Linux before, the Linux version of the Eee PC 900 is worth considering. It's more expensive than the Windows XP version, but it does have a larger internal storage capacity, and we feel that it's easier to use.

An excellent choice for on-the-road business users, offering great performance and excellent battery life. Its size, weight and battery life make it very portable and it's got some style, too.

It has been out for a while now, but the original Eee PC is still great value and one of the best super-portable laptops on the market.

The Fujitsu Lifebook U1010 3.5G is a great example of the increasingly popular ultra mobile PCs. It's easily held and is comfortable to use while also being extremely portable. If the size and weight weren't enough to get you excited then the addition of 3.5G HSDPA speeds of up to 7.2Mbps should help.

The VAIO is an excellent option for anyone after an ultraportable with good performance, solid battery life and an excellent design.

The Sony Vaio SZ15GP/B is a great entry level unit for people who want to get mobile but don't need a monster laptop.

If you're looking for top comfort and full features in an ultraportable, you'll find them all in the XPS M1210.

Although the Toshiba Portege R500 is clearly not a power user's choice, its lightweight frame, small size and good battery life make it an excellent choice for simple tasks such as email, Web surfing and simple office applications while travelling for business.
