Interesting, though I have to wonder if that's necessarily true; it seems that you could designate a button using only rectangles and solid colors in a way that would be clear and unambiguous (e.g. Google+'s buttons). Either way, interesting application of Norman's ideas of 'affordances.' DoET is a perennial favorite of mine.

>(e.g. Google+'s buttons)

They actually have slightly rounded corners, an outline and subtle gradient going from top to bottom that hint at three dimensionality and offers affordance. There's also a slight darkening on mouse-over which suggests they're interactive and can be pressed in.
