Is it though? 3 million units sold becomes less impressive considering all the cable boxes and Live subscribers out there. Not to mention the burgeoning smart tv market, and the fact that TiVo is even still breathing.
Apple is an undeniable tech behemoth, but they really have yet to dominate the living-room space, and there are services out there (including the constantly evolving Xbox Live) that are ensuring they probably never will. So I don't think Nintendo is in a position where they
have to compete with Apple, at least not in the console space.
Nor do I think that anybody planning to buy an iPad is going to be enticed to buy the Wii U instead, or vice versa. They're not similar devices just because they both feature touch screens. The iPad's biggest strength is that its slim and portable. It can function as a computer replacement on the go. The upad can't. It's a terminal; a controller with a screen on it and nothing more. It's every bit reliant on the console as if it were tethered to it. It'll be able to provide superior gaming to the iPad, but that's because it's a
console, not an iPad competitor.
Of course Nintendo should add extra functionality to take advantage of the touch screen, but I think it would be a huge waste of resources if Nintendo approached next gen as though
Apple were their competition.
