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

It's rare to find a notebook as versatile as the LifeBook P1610. There are certainly compromises to be made for its tiny frame and convertible design, but if blistering performance isn't essential, the P1610 is well worth a look.

Exceptional battery life and a compact design make the nc2400 a great option for those willing to sacrifice some performance.

The Fujitsu P7230 ultra portable notebook doesn't offer stellar performance, but its impressive battery life will keep you up and running for long periods of time and its light-weight design with the 10in screen make it very easy to carry around.

If your business or studies require full functionality from your notebook while away from power and network connections then you can't go wrong with the X60. While it's expensive, it's still competitively priced in its class.

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

The ThinkPad X61 is well-built and very portable, which makes it suitable for the road warrior. However, it doesn't ship with an optical drive.

The Fujitsu Q2010 is an ideal mobile tool with a lightweight design and integrated 3G making it great for use on the road. It lacks grunt but should be more than enough for office applications and keeping intouch with colleagues.

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. However, for the premium price it is short on ports and other features, a disappointment despite the advantages of its rugged design.

As a multi-purpose business notebook, the Lenovo 3000 V200 performs admirably well in almost every area. However, those after a highly portable unit are likely to find themselves a little weighed down.

There's no doubt this unit is ultraportable and it did well in our battery testing, but with a $5499 price tag it's just too expensive.

A mixture of smartphone and notebook, this stylish ultraportable from HTC lacks the strengths of either category and will not satisfy business users on the go.
