Again, I think that this portends a paradigm shift for workstations in general.
I'm an artist by trade, have been digital since '84 but have missed the old drawing board since then. I want a touch sensitive screen with no lag, in the form of a traditional drawing board, that I can use a stylus and my near atrophied left hand interactively. I want to move the "paper" and draw at the same time like in the real world. A nice 42" "DIGITABLE" with legs or a stand to keep it at a drawing angle woud do nicely. The 24"iMac has been a godsend in the screen real estate area, but is still "old school". The whole look-up to draw-down wacom tablet world is about to be shook up.
Beyond the drawing stuff it could mimic any and all things like audio mixing boards, film editing etc. Even the clutter of my actual desk. This multi-touch sensitive screen stuff just makes me drool.
The "workstation" as a drawing board, or as I used to call it the "digi-table" is an obvious next step in the evolution of the professional studio. Once the ergonomics of the size/flexibility of the work area are worked out the possibilities are endless.
Exciting times indeed.
