Behold: The Piano Of The Future

   +  = 

If I were a digital-piano maker, I'd be working feverishly to develop a model with a built-in touchscreen display to replace or supplement sheet music. Pianists would be able to select measures, click on them and hear instantly how they're supposed to sound. They also would be able to browse and download music at will, plus research composers and the history behind the music -- a practice that can help musicians play pieces as they were intended to be played.
