StaffPad's one of those apps that makes me wish I was a musician. I've dabbled in music programs like Sibelius before, but StaffPad makes it and other music notation apps look complicated in comparison. The way StaffPad uses the stylus to write music feels so natural, it's surprising that it hasn't been done before.
I'd love to see StaffPad (or something like it) used to actually teach music theory - it'd be awesome to learn by manipulating a score in real-time to hear how it changes.
