It's not hard to see that certain games can teach, Nintendo doing this will both do that AND get them money.
Now, on the computer/paper, that sounds like an awesome Idea, but then, actually getting DS'S to be a part of school learning? It sounds like....a longshot. It could work, but then, the chances it will fail are somewhat up there, A DS can work where you aren't completely forced to go from point to point, shut up and listen to an anonymous man/woman all day. I mean, you know, in schools.....So, good luck with that Nintendo!
