Top five reviews

Palm Pre

The Palm Pre is one of the most hotly anticipated mobile phones of 2009. Hailed as the first phone to have a chance of stealing the limelight from the Apple iPhone, it's gearing up to make its debut on UK shores.

LG 42SL9000

LG's 42-inch LCD TV might well come to be remembered as one of the sets that put LED backlighting firmly on the map. It's a gorgeous-looking television, with stunning picture quality.

HTC Touch2

As a Windows Phone, the HTC Touch2 is among the first batch of mobile phones to launch with Windows Mobile 6.5 included as standard. It's a pretty decent effort too, although it's aimed more at business users.

Motorola Dext MB200

Motorola has been silent for a long time, but it has finally brought out the Dext – the first phone in years that can be spoken of in the same breath as the Palm Pre and HTC Hero.

Sony PSP Go

The Go is the latest version of the Sony PSP handheld gaming console. The controls now slide out from under the screen, so it's a lot smaller than previous versions – and it's a lot more fun too.
