Sony Ericsson has unveiled the latest addition to its Walkman line-up, which although on the small side will generate lots of consumer appeal - or so the company hopes.

Sony Ericsson's Xmini: tiny, light

The Xmini measures just 75 x 44 x 18mm, which means sadly that it only features a wee 1.8in, 240 x 320 display. The slider phone also has tiny physical keys that, from the look of it, might be tricky to use at the best of times, let alone calling a cab after a night on the tiles.

All this miniaturisation means the talker only weighs 75g, but it's also light on features. There’s no mention of an integrated camera, and although the Xmini has a goodd 4GB of on-board memory, there’s no memory slot for more.

However, Bluetooth is integrated into the talker.

The Sony Ericsson Xmini is set to be launched in Japan later this month. A price hasn’t been announced yet, but we do know that the phone will be available in a range of sickly colours, including a green body with purple keys, and a purple body with pink keys.
