Sony Ericsson Xperia family portrait at MWC 2011

Sony Ericsson shook up MWC before it had even begun this year by introducing the Xperia Play -- the world's first PlayStation Certified phone -- alongside a pair of new members of its Xperia line of smartphones, the midrange Neo and QWERTY-sliding Pro. Taken together with the Xperia Arc that debuted at CES in January, this little bunch of Android Gingerbread runners will form SE's principal attack on the ever-fickle smartphone consumer's wallet this year.
