I agree with all you say Fizzy. I came from the 505, I had the silver and red ones (and yes the red is sexy lol)....my 600 is the black one as I wanted to keep all my readers different colours....
I love the new features on the 600 and cannot imagine not having them now. It is a real pleasure to use, though I will keep both my 505's as backups as I love them too and now can carry one around with me and not be as worried about breaking it as I have 3 readers now.
I too may increase the font to M when reading is not so good lighting, same as you I create my files in the font size I prefer as S.
Yes, the screen is not as clear, the reflectiveness can be an issue if you don't learn how to compensate, by angling during the day or using a light when needed. I use my mighty bright clip on, and with that the screen looks as unreflective as my 505 and almost as good contrast too, so I am very happy now, using my mighty bright and don't feel the need to increase font size when using it. After all, I should use it far more than I do for my eyes sake lol the 600 makes sure I light up more than I previously did ......
I got the proporta leather case for mine and love it. It is beautiful quality, nicely padded and very sturdy, making the reader feel protected and comfy, it folds back real easy too, and stays open if you don't want to fold it back.
