Industrial design is one thing - the apps are another. Here's a game-changer:
Apple - iPad - From the App Store - Play and record music with GarageBand.
The iPad is already making serious inroads with musicians and is changing the way that music is *made*, not just consumed. The implications for performance and education are striking.
Unfortunately I don't think the iPad1 has the horsepower to run this, nor does it have the gyros to deal with the touch sensitivity. But such is progress.
