We couldn't find a weak point - and believe us, we put the Acer through its paces. With a WorldBench score of 90, it'll breeze through most tasks. If you're looking for something powerful with great entertainment potential then look no further than the Acer Aspire 9504WSMi.

This is a device that suffers from a slow processor, low battery life and strong competition from the identically priced Fujitsu T1010 and HP tx2522. If you're interested in a portable device with good connectivity features then have a look — just don't expect brilliant performance.

They've finally done it — the Sony VAIO VGN-Z16GN/B is a great mix of power and style for those who can swallow the $2999 price tag. Users will just have to make sure they treat it carefully, especially when dealing with the screen.

While not for everyone, the nc6400 proved to be a solid choice for those after a business notebook, offering reasonable performance combined with optional 3G internet built in.

The U400 is a good size for travellers, has plenty of connectivity and good speed, and it's also well priced, but its battery life is short.

Although Dell's build quality is once again a winner, the Inspiron 9400 is lacking in other areas, mainly looks and graphics.

If you’re looking for a desktop replacement with processing power, plenty of storage, an excellent screen and great connectivity options then the Dell Studio 17 (1735) is a hard product to beat.

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 NEC Versa E6510-2505DR is a very cost-effective and powerful machine that is difficult to fault. Although the faux leather looks and feels fake and the non-standard keyboard may occasionally cause typing errors, users who can look past these faults will find it to be an excellent device.

Apple’s greenest notebook ever is also one of its best. The MacBook Pro is overpriced, but you certainly get a powerful and exquisitely designed machine for your hard-earned cash. It’s not perfect, but using it is a largely positive experience on the whole.

A decent, but not particularly inspiring machine, the Tecra A6 will suit those who need an affordable business notebook.
