A look through Sony Ericsson's Pureness phone

The Xperia Pureness comes with the tagline: 'Talk. Text. Time.'

However, the idea this represents — that the handset will do nothing more than voice calling, text messaging and waking the user up — has given way to the addition of more features, Sony Ericsson designer Daniel Mauritzson said at the London launch.

These features include video streaming, web browsing, email, sound recording, music playback and FM radio.
