It might be useful for topics like Maths and English, but you can only learn so much by using that. Such as in subjects like P.E, it is mostly a practical topic, so it wouldn't really work with it.
Plus, I don't see the difference between learning off a Nintendo DS or other technology then by learning out of a Text Book.
But I do think that as time passes, Text Books will be faded out, and Technology will take over.
