When we first mentioned Microsoft's new keyboard idea, it was mentioned that there would be a contest, and students all over the place would be competing to create the coolest applications for the device. Well, the contest is over and the winners have been announced. So if you were thinking of entering, too bad. You'll have to wait for the multi-touch mouse contest.So they had three categories: most useful, best implementation, and most creative. Remember, these are just demos made by students, so forgive their lack of polish. The demos, I mean, not the students.
