But, much like the upcoming Microsoft Surface, one of the more noticeable features of the Xperia Tablet S is the cover that features a built-in physical keyboard, sold separately for $100.
Who wants an Android tablet anyway? The phones themselves are so huge you can just get one of them (a la the Galaxy Note, and the second one is coming soon)... The Surface tablet looks nice though. I'll wait for the full Windows 8 tablet though because I can't deal with Windows RT.
