>> without addressing the obvious point that an iPad can be a million things other than a piano.
I think you're missing the point. He's saying we should work toward creating a new kind of technology where the ipad would really feel like a piano when you're on the "piano app", but feel very differently for other apps.
What you're saying is that you don't think that such technology could ever exist; BV thinks otherwise and he's working toward that vision. He's also saying that we shouldn't take the future for granted as if a technology will just suddenly appear. It takes hard work, funding and a clear vision.
I can think of a few ways about how we could add tactile touch to a dynamic interface (I.e. turning a piano 2D screen to a real experience). VR is going in that direction (to see 3D from a 2D screen) and you can imagine some sensors at the tip of your fingers where depending where you touch you'd feel something different. Again, that's just an idea, there are many ways it could be achieved.
