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.

This Linux version of the Aspire One is easy to use and has a solid-state drive, but the Windows XP version has better memory and storage capacity for only $100 more. Furthermore, Acer will also release versions with built-in 3G modules. It's really a case of waiting for the new versions to arrive, unless the portability and ease of use of this unit catch your fancy.

While Ferrari fans are going to want to splurge for the luxury of a true Ferrari sponsored notebook, unlike the cars we can't justify the cost for the performance. The feature-set isn't bad and will get you by if you've got to have the Ferrari name, but the rest of us have no sensible reason to buy this machine at this price.

The Acer Aspire 2920-302G25Mn is an ultraportable 're-imagining' of the all-purpose Gemstone series; offering a similar performance in a lightweight package. Provided you can overlook its garish interior, there's plenty to love about this little gem of a performer.

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.

The 1000H is the best Eee PC yet. It's got a larger screen and a larger keyboard than its predecessors, it's faster and it's also got a much larger storage capacity. It's perfect for on-the-go types who want something light and functional to work on.

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

Lightweight and fully equipped, the 1.8 kilogram W5A goes one step further than most ultraportables, coming with a swivel Webcam.

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.
