I agree. I don't want an iPhone/iPad/iPod as a workstation. How about keeping a version of OSX at least semi-professional.
How is it not professional?
I will still be running Maya, ZBrush, Unity, Houdini, Corel Painter, After Effects, Photoshop, etc on it, I'll just be able to do it while not having to keep 20 million things open since Notification Center will be there.
I think people are over thinking this...
