It looks great and has fast specifications for an ultraportable laptop. It's a good thing it comes with a second, larger battery though, because its small battery produced a very low run-time in our tests. Nevertheless, if it's a lightweight powerhouse that you want, this one is ideal.

While it has a fast CPU and good features, such as built-in 3G connectivity, the U6Sg is let down by poor battery life. This is a major drawback for a unit that's pitched at style-conscious road warriors. If considering this unit, you should either opt for the slower CPU, or the larger, 9-cell battery.

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 Flybook VM's lifting screen is very useful and the unit is comfortable to use overall. It has enough power for typical office applications and even Photoshop, and its screen produced rich colours. We wish it had at least one more USB port and an SD card reader. Apart from that, we think this is a great choice for anyone after a comfortable ultraportable unit.

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.

We truly wanted to love the Asus U1F (1P010E), but its lack of a built-in optical drive and poor graphics chip dampened our ardour. Nevertheless, it remains a handsome choice for business use and web browsing.

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 mid-sized widescreen has plenty of power and a sizable, speedy hard disk, and it's backed by a three-year warranty.

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.

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

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

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