It's like an iPhone with a full slide-out keyboard. The touch-screen is impressive, with a zoom function that makes web pages very readable and, by brushing the screen with your finger, it's easy to scroll through content including pictures, tunes and maps.
Some of the applications are mind-blowing, including one which allows users to scan a bar code in a shop and get an instant price check at other shops and online outlets to see if it's cheaper elsewhere.
