A new breed of mobile phone is set to change how we think of the devices that millions of us carry every day: one, billed as the most powerful smartphone in the world, can even power its own laptop - the Motorola Atrix.

The Atrix challenges the distinction between mobile and computer. It is an Android smart phone that can be plugged into a range of docks that convert it into a sleek netbook, a media centre, a sat-nav or even a humble alarm clock.

Motorola’s solution is to make it a digital hub: plug your mobile into a dock attached to your TV and it will act as a media server for films, TV and music. The Lapdock offers all the laptop most users ever need. A wireless Bluetooth keyboard is also available, as is another dock for use on the bedside table.
