The Xperia is the world’s first mobile phone with a transparent liquid crystal LCD screen, offering ground-breaking miniaturisation technology in the battery, memory card and antenna with an overall industrial design. The keys are hidden and only light up when touched. The subtle illumination, with call and message notification, transforms the handset from an object of design to a phone only when needed. The phone comes in Black and is just 102x43x13mm and weighs in at just 70 grammes. It boasts a music player, which comes with album art capability, trackID and mega bass. It also has a web-browser and in the unlikely event that something should go wrong with the phone, Sony have provided a priority line which promises a replacement within 48 hours.
