Good point. Perhaps the problem is the work station and not the device itself. Still, the way tablets work now, they have to be at a fairly low angle, or one's hands will quickly get tired. That coupled with lack of real world applications doesn't seem to align very well with tablet's possible ubiquitous future.

Maybe it's better the way it is. Maybe having a machine for "work" and machine for "play" is how we keep things intuitive, modular, and clean.
