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.

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.

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.

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.

The Fujitsu LifeBook S6311 is a professional notebook with some nice features. It performed well in our tests and it's fairly priced for it's quality.

Although there's a notable premium on the solid-state hard drive and ultra-portables don't often come cheap anyway, this is a good little buy. It's got enough power to handle the most basic tasks and its implementation of flash memory should please those wanting to be on the cutting edge.

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.

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