The VAIO VGN-UX17 is a revolutionary entry into the portable notebook space, offering a fully fledged Windows XP device that is small enough to fit into the palm of your hand. We'd like to see further developments, but it still should appeal to those looking for portability and full PC functionality.

The Libretto's miniature size and light weight will attract veterans of the road who want to travel without being encumbered.

The Lenovo 3000 V100 is a good all round notebook that also happens to be fairly small.

Spring for the extra battery (at an extra charge) to add needed life to this otherwise fine and very light travelling companion.

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.

The OQO E2 is quite an impressive little design with some good connectivity and would suite a number of tasks, as long as they require more portability than power

This is a laptop for the fashion-conscious user who wants to get some work done on the road. It has good connectivity features and it is small and easy to carry, but don't expect to be able to perform taxing tasks on it.

The screen may have a poor viewing angle, but the rest of this portable business option is pleasant to use. The LifeBook P8010 may not be as thin as some of its closest competitors but it's still a very portable unit.

This laptop is the perfect size for the road warrior who wants to get online while on the go, and who also wants something that looks flashy. Its colour might be a little too feminine for most guys' taste, but women might find it irresistible.

The ASUS has big application performance and a sleek physical appearance.
