Sony Ericsson Xperia X10
Sony Ericsson has taken a while to come up with an Android-based handset, and the Xperia X10, it has to be said at the outset, is probably not the offering to tempt business users. A forthcoming variant, the tiny Xperia X10 mini pro might appeal more, as it has a slide-out QWERTY keyboard while sharing elements of the Xperia X10's somewhat quirky user interface.
