Only thing I can think of is "typing anywhere" which you'd have a problem doing with the wii (less you had a battery and a portable TV, but eh, just stick to the DS then)
I will say one thing, they better make software to let it talk to the web browser on the DS (or at least, the 3DS (being april, it could be 3DS (that wouldn't be April 1st would it?

))) While I don't mind using the thing on occasion, I don't like typing on it, full virtual keyboard or no, just to small.
Anyhow, while i probably don't need a typing tutor, weird stuff like this just screams "get me" to me, and I must have one.
