iPad will burn out you eyes after some hours of reading. The whole point of the readers is the special display, what really looks like a book page, and it doesn't vibrate. Very good for the eyes. When i first saw an reader i thought it is just a promotional machine, and it isn't functioning. Then i discovered, that it is actually turned on, and what i see isn't a piece of paper behind a glass, but a working display - but i couldn't tell the difference for the first sight.
