You might also consider the OLPC XO-1 (http://en.wikipedia.org/wiki/OLPC_XO-1) which can fold up into an e-book reader. The LCD screen can go into grayscale mode which is apparently pretty nice for reading. It also has a full keyboard and linux OS for browsing, apps, etc.
ah k thanks for that, but i am more in the market for a professional higher end one with the latest ebook technology.
Can it read CHM format?
No I am pretty sure it cannot.
My brother has the PRS-505 and he seems to like it, I like it too I just wish it had a little bigger screen
