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

An ultralight tablet PC that is a little weak on character recognition, and too high on price.

Unfortunately there is no microphone, and the specs are a bit weak where it matters.

This classy business notebook from Sony helps you get the job done in style.

An ultra-portable ideal for road warriors, the VAIO TX47 offers outstanding battery life, and a stylish design.

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.

Its screen is hard to view properly, but apart from that, the R500 is a genuine lightweight. At under 1kg, and with battery life longer than four hours, it's perfect for users who work long ours while on the road.

It's not perfect, but its portable size and relatively powerful specifications make this notebook stand out. It's well-suited to anyone who wants a compact device that doesn't sacrifice features.

It’s good to see that Toshiba has improved this notebook and rectified some of the small performance flaws we noticed in the earlier M800. Overall the upgrade has seen small performance gains primarily in the graphics department. It's a great ultraportable notebook that offers strong performance despite its small size, and it is a joy to use on the go.

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'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.
