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.

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 lack of a built-in optical drive and the so-so keyboard mar this lightweight notebook; however, the price is reasonable for an ultraportable.

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 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.

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 U3 offers HDMI and eSATA ports, integrated HSDPA and GPS and features a dual graphics setup. Whether or not you are willing to sacrifice an internal optical drive for these features will determine if this stylish ultraportable is for you.

This is a laptop for the fashion-conscious user who wants to get some work done on the road. It has good connectivity features and it is small and easy to carry, but don't expect to be able to perform taxing tasks on it.

It has been out for a while now, but the original Eee PC is still great value and one of the best super-portable laptops on the market.

Physically, it's the same as the Linux version, and it has less storage space, but it does feel a little faster and it's much better suited to playing videos.
