In point of fact, no, I don't think pinch to zoom is the only thing multi-touch is good for. I have a vita, I have a tablet. I have, indeed, partaken of the rope cutting and the ninja fruiting.
It would be ideal from an interface flexibility standpoint if the Wii U controller had multi-touch... but of everything else it COULD lack, that is the least important thing for, ironically, the hardcore market.
The ones most upset at Nintendo's E3 showing. The ones who wish the Wii U padlet didn't even exist. And who all say they're going to run out and buy a Wii U Pro Pad to play like real gamers.
So in this sense, Nintendo really can't win.
Leave out multitouch, concerned enthusiast gamers will say they're crippling the system. While seemingly an equal number of enthusiast gamers will say who needs a screen at all, get rid of it, and get a real game pad.
The Wii U.
It's sufficient.
The system was originally called Wii Ultimate.
But shaving off seven letters saved enough to cover the blue LED around the home button.
