Hey SonyFan! I agree I really like my 700. And your correct, at least on the hardware side, I see the 600 as a step back. But for those who do not need a lighting solution, it looks to be a great reader. I would love to have the dictionary support, and freehand annotation ability, but perhaps we can hope for a firmware update for the 700. Well, we can dream anyway.
I am very interested in the Daily edition though (2121). I am hoping there will be a good option for lighting on that model! (yeah, I know, "get a lamp, Donnageddon!")
