What's great about his axe isn't that it looks like a normal instrument -- it's the way it maps touchscreen interfacing to the guitar form. I'm an electronic musician too and have seen plenty of history and modern experimentation; something that takes his touchscreen-guitar idea to the next level (full touchscreen neck?) has much more expressive potential than a normal guitar with a MIDI-transcribing pickup.

Plus it doesn't throw away one of the biggest lessons of rock: people will scream for a guy with a guitar in a way that they won't for someone behind a piano (or god forbid, a theremin).
