If it were to be unctional at both, it would be exemplary at neither. I mean, this best is beautiful because it uses the piano's body aesthetic. I think it'd jst be kind of tacky to have it actually be usable in both capacities, like an old synthesizer with glowing orange display, or fruity loops.

I wish there was more artistry, like this, in the mass market. Look how well iMacs cleaned up, at least partly because they were more pleasing to the eye than most PCs.
