Sony has just announced that the Android 4.0 update for its Tablet S is now available and should be rolling out to owners —j ust connect your Tablet S to Wi-Fi and you should be prompted for a system update. It's good to see Sony living up to its word and delivering this update when it said it would, though we're still waiting for the Tablet P to receive its Ice Cream Sandwich update. To go along with this update, Sony's offering the Tablet S at a bit of a discount — if you buy between now and May 12th, you'll receive $50 as well as a free cradle accessory. This puts the Tablet S at $349 for the 16GB model, and while it isn't the best Android tablet we've ever used, the infusion of Ice Cream Sandwich should help give it a new lease on life.
