If you consider battery life and light weight the most important laptop criteria, give the LifeBook P7010 a close look. You could probably live with this 1.5-kilogram unit's less-than-perfect keyboard and screen.

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.

It's well-suited to road warriors thanks to its light weight and built-in 3G module, but it's still not the perfect laptop. If you're going to go for the R500, opt for a solid-state drive instead of a conventional hard drive.

Although the Panasonic Toughbook CF-W5 is not the most stylish or powerful machine, it does offer some good battery life and should take a few knocks without any trouble.

Alienware takes a nice step out of the high-power desktop world into the ultraportable market with the Sentia m3200

This VAIO is stylish and redefines the meaning of the term ultra-portable. We wouldn't recommend it if you are just looking for a notebook, but if portability is your number one concern, then you can't go past the VGN-TX27GP.

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