The Xperia X10 is the first ever mobile from Sony Ericsson to use Google's Android smartphone operating system. And what a debut phone it is.
In an in-depth review, Top10 gave the phone an outstanding 8/10, with particular praise reserved for its touchscreen user interface and video recording and viewing capabilities.
As well as the great features listed above, the phone comes with the 1.6 version of Android pre-installed. However, at a later date users will be able to upgrade to the latest 2.1 version of the platform - effectively meaning they get a state of the art, brand new mobile for no extra charge.
