E-ink doesn't work like a CRT or an LCD or plasma or whatever other active display you'd care to name. Since it works by moving physical particles around via an
EMF (which is turned totally off between display changes), there's nothing
to burn in.
Consider this, when the screen is blank, what you actually have is all the white particles on the top and all the black particles at the bottom, but all the particles (of both colors) are
still there. They don't care if they're all together, mixed up, top, bottom, whatever, because they're just sitting where they were left, and they'll go on sitting where they're left until they're moved somewhere else.
Perhaps they will lose their charge over an extended time, and stop working then, but it won't have anything at all to do with what position (top/bottom) they were left in or for how long -- they just aren't affected by that.
