I've just finished reading a book on my PW2 and in my opinion, it's much improved over the PW1. The recent pictures here look nothing at all like my PW2 (I've tried unsuccessfully to photograph it). Mine is very evenly colored with a very faint beige tint. No screen imperfections at all. The helvetica font is nice and dark. Footnotes are now handled incredibly well.
Everyone sees things differently and I'm just sorry that once again this year, MR PW buyers have angst over what real or imagined "imperfections" their PW will have
Personally, I never put much import in internet comments as you never know the agenda of posters (including myself of course). But for me only, this is the best ereader currently available.
