What I've never understood is this: the eInk works by having a Sagan ("billyuns and billyuns") of tiny particles, coated white on one side and black on the other. Apply charge, flip them all one way, selectively apply charge to flip SOME of them back the other way.

So... why do they have to flash BLACK and then turn some white. Why can't they flash WHITE, and then turn some of them black. That would certainly make for a far more esthetically pleasing experience.

I'm sure there's a reason, but still, curiosity and the cat...
