[quote="Ashley"]Also why not just make a mobile or tablet that can plug in to a TV, with wireless controllers?[/quote]
The entire point of this thing is to make a "console", not a tablet.
Making it a tablet would also be kind of dumb. First, they would have to incorpotate a screen, increasing production costs further. Second, the tablet market is pretty saturated. Everyone seems to be making tablets. Microsoft, Gamestop, Amazon, etc etc. The console market is anything but saturated. There's three consoles, period, and to get on one of those you HAVE to be backed by a publisher.
