Gimmick: PlayStation controller
The first "PlayStation-certified" phone, the Xperia Play converts from an Android Phone to a handheld PlayStation device by pulling out the controller drawer. The Xperia Play will come with pre-loaded games, and users can download more PlayStation games from an online store.
Not for you? Sony Ericsson also unveiled two more nearly identical Xperia phones, the Neo and the Pro, the latter of which has a pull-out keyboard rather than a pull-out controller.
NEXT: HTC Salsa and HTC ChaCha
