A major leak on Wednesday has unearthed Sony's plans to finally join the mobile tablet space. So far only called the S1, the 9.4-inch tablet would run a customized version of Android 3.0. The device spotted by Engadget would be focused heavily on Sony's Qriocity media service and would come with games from the PS1 era likely using PlayStation Suite, the Bravia remote app and some form of PlayStation integration.
