What I'm interested in is something that takes hand drawn input and converts it to expressions that can be evaluated. A dedicated keyboard for math has been immensely helpful to me, as well, because it speeds up the input more than any software only solution I've tried. But there are always things which require some thought about how to enter them in. Not having to do that conversion myself would be pretty nice. I think there's some potential there.
