I'm in the market for a new iPad. I had the IPA 2 and it recently died. The lowest level iPad will probably suit me fine but I have reservations due to it not having an anti-reflective coating. I like to read on it in my back yard. Will there be a big difference in iPads with, and without, the coating? I should mention that when I read I invert the colors so I'm reading white letters on a black background. I find that I can't see my floaters when I do it this way. Thanks.
