For all its impressive functionality, there's one smartphone specification that has long tipped the scales in the wrong direction: the small matter of size. Luckily, there's now a way to fit all those telephonic essentials into a device that (genuinely) fits in the palm of your hand. It's called the X10 Mini Pro.

Sony Ericsson's miniature multitasker – the latest addition to its Xperia family – squeezes a reassuringly rigid QWERTY keypad into its 90 x 52 x 17mm footprint, along with an Android operating system, blissfully simple email and social networking features, 5MP camera and flash, touch screen, high speed internet, aGPS and expandable storage.

The MP3 player/FM radio also punches well above the device's 120g weight, providing the sort of detailed acoustics many of its rivals lack. Our only gripe would be that compiling music playlists remains a little too fiddly for our liking, but it doesn't detract from the fact that this is a tiny phone with enormous potential.
