The HP 2133 Mini-Note PC (FJ100PA) is designed to be a true ultraportable device, sturdy enough to take some knocks and light enough for everyday use. Business users will appreciate the connectivity and networking options. When compared in terms of specifications, performance and value of the FH441PA model it doesn’t shine as brightly.

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.

If you’re not quite rich enough to own a luxury sports car, but still have more money than sense, then the Asus-Lamborghini V3 might just be the status symbol you're looking for. However, it isn’t that fast for a Lamborghini notebook, and is exorbitantly priced for what it offers.

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.

The Fujitsu LifeBook P7120 is an attractive and cleverly designed notebook with all the bells and whistles of some much more expensive models.

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.

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.

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.

The VAIO VGN-UX17 is a revolutionary entry into the portable notebook space, offering a fully fledged Windows XP device that is small enough to fit into the palm of your hand. We'd like to see further developments, but it still should appeal to those looking for portability and full PC functionality.

For its size and price this Acer is a great purchase. It has a strong selection of connectivity options crammed into a small package and good battery life as well.

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

A solid ultraportable ultimately let down by poor battery life.
