Sony's steaming games service will only need a DualShock controller and a hefty wallet to get you playing PlayStation games from the classic 20 year-old model to the latest PS4 titles, all via the power of the cloud (and a decent network connection). Interesting to see Samsung ditch Google's Android TV idea for its own OS.
Of course, if you're quite happy with your perfect plasma or recent LED TV, why bother and just pick up a PlayStation TV or one of the many Android gadgets to get some cheap gaming going.
