Theres simply no way that the tablet is going to catch on as a controller type. I can see it catching on as like a "im gonna play mario on this thing while my girlfriend watches Americas got talent" but overall it just doesnt look like it;ll be usable for long periods. Which means it;ll be an optional control scheme.
So whats everyone whining about?
And yeah Sony actually ALREADY has a tablet controller...im just not sure if you can do much with it yet.

edwardsdv and swordz9 are basically the comedy heel tag team of this topic, why would people be taking them seriously?
