OnLive's cloud gaming service has finally come to tablets and smartphones. Released first for the PC and then on a separate, TV-friendly console, OnLive apps can now be downloaded for iOS and Android devices. While you'll have to shell out $50 for wireless controller, the OnLive apps are supposed to be free. If you download now, OnLive will throw in free access to Lego Batman, too. Other games will have to be purchased through the app on Android or on a separate PC for iOS devices.
