Looks like Kobo does a much better job of distributing light evenly. I don't see any dark shadow areas like I do on almost all the PW photos, even the official Amazon photos. But it looks like the same sort of discolorations. I think this first generation of light layered e-readers needs a lot of improvement! I'll wait until next year. I decided to get a Nexus 7 for night reading. Even if an iPad Mini gets released there could be issues with them too, so better to wait on that until next year as well.
