Being able to stream console-quality games to mobile phones is novel, but the touch screen controls offered via OnLive didn't really impress us much. If only there were an Android-powered mobile device that also offered physical buttons for gameplay...

Oh yeah, Sony made one: it's called the Xperia Play. OnLive has now been updated to support the "PlayStation Phone," enabling Play owners to play "almost all" games in the OnLive library.

Thanks to the slide-out controls of the Play, Xperia owners can play games like Saints Row: The Third and Assassin's Creed Revelations via OnLive's streaming client.

"From the moment we launched our OnLive Android app, gamers began asking about Sony Ericsson Xperia PLAY game control support," OnLive founder Steve Perlman said in a press release.

If you don't have an Xperia Play but want button controls, OnLive also sells a proprietary Bluetooth controller for $50. An iOS version of the OnLive client is in the works as well.
