Sony's Tablet S (or "S1") was released over a year ago to little hubbub. Still, that's not keeping the increasingly-awesome Sony from shooting a new software update out for it with many of the software features of its successor, the Xperia Tablet S. None of the features are especially mind-blowing, but they certainly add functionality:
Redesigned media players
More "Small" (floating) apps
Expanded functionality for the remote control app
Social Feed Reader Cloud has been updated to Socialife
Oddly, they suggest people also download Watch Now from the Play store
Otherwise, things stay basically the same. There are no Android updates included (still 4.0.3) nor other changes, from what we can see.
