The NEC Versa E6210 looks nice and is a good size for those on the road. The battery life didn't impress us, but will be fine for the casual user, as will the performance of this machine.

The U1010 is about twice the size of a smart-phone, yet it's a fully-fledged Windows Vista-based tablet PC. It's suitable for professional users, or even regular travellers, who want a very mobile device with all the functionality of a typical computer. Unfortunately, it lacks built-in 3G features.

The Fujitsu Lifebook U1010 3.5G is a great example of the increasingly popular ultra mobile PCs. It's easily held and is comfortable to use while also being extremely portable. If the size and weight weren't enough to get you excited then the addition of 3.5G HSDPA speeds of up to 7.2Mbps should help.

A solid ultraportable ultimately let down by poor battery life.

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.

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

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.

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.

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.

The MacBook Air is a superbly crafted notebook, but this niche product isn't for everyone. Its lack of optical drive, FireWire and Ethernet ports deem it inadequate for power or everyday users. Regardless, it functions well as a secondary device for frequent travellers, or those who require basic, hassle-free computing.

A good ultraportable, the U5F offers excellent battery life and solid performance wrapped up in a stylish and attractive package.

Well built and full of features, this lightweight laptop is perfect for professional users who need good speed and ease of use while on the road.
