The world may be forgetting about the Sony Tablet S, but Sony isn't. And that's a good thing. UK based Tablet S owners should be seeing an update pushing out to them right about now.
The update doesn't bump the Android version any further than the current 4.0.3, and at only 9MB isn't bringing anything massive to the tablet. But, the fellas over at Coolsmartphone are reporting that they're seeing a considerable improvement in performance. Overall they're seeing a distinct change in navigating through the tablets UI and menus, although app performance hasn't changed.
In any case, bug fixes and optimizations are as good a reason as any to update a device, so if you've got a Tablet S let us know in the comments below if you're seeing any changes.
