I didn't say anything about spelling.
I meant that this could cause carpal tunnel with the constant wrist flicking and movement. After watching the conference and the video they played, I believe they are going to be using the controller for the next Mario game and we all know how much you have to jump in a Mario game.
Again, I haven't tried it so I don't know how it will feel, but there seems to be a lot of concern from all types of gamers.
