I'd love for someone to try and put this into real hardware.

Computers have advanced but calculators haven't.

Calculators are only focused on school kids, not on people who really need to get things done.

I'd love to have octave or scipy on a piece of dedicated hardware.

A Mathematica style program for tablets that could convert handwritten math using common notation into symbolic constructs would be absolutely amazing.

Doesn't Windows do this? Last time I tried it it was amazingly accurate.
