This year's Mobile World Congress had a lot to offer, from the latest handsets to 4G-connected cars.
The biggest hitter at the show was clearly Android. With neither Nokia nor Apple having a presence at the show itself, the field was clear for a plethora of Google-OS'd handsets and services.
One of the most unusual Android devices to be shown was Sony Ericsson's X10 Mini Pro (pictured above) — a very small handset with a Qwerty keypad. The phone is so small for a touchscreen device — its screen measures 2.55 inches diagonally — that Sony Ericsson had to create a specially modified version of Android, based on icons in the corners, that would allow for one-handed operation.
Despite the petite dimensions of the keyboard, ZDNet UK found it to be surprisingly usable.
