Successor to the best selling Galaxy S, the S2 is ultra light. With a dual core processor, superb screen, and thin casing, this device certainly has that 'wow' factor.

A mid-range touch device in a busy market, the Ace comes up trumps with its broad feature set and good build quality. Still lets itself down with a lacklustre internet performance.

Great hardware, operating system, and apps come together in a brilliant smartphone. Stunning industrial design, super sharp screen, and video calling are among many improvements.

Smartphones have come a long way but the Xperia S could be the best one without the Ericsson tag line. The brilliantly clear screen and high tech camera are topped only by the powerful processor inside.

Improves slightly on the already great iPhone 3G, adding a compass, voice memos, video recording, and a better camera. As a whole, it's the world's best touchscreen phone.
