Thanks Bob for your insight. All information presented here is extremely useful for us who were either thinking about getting a Reader or just plain newbies.
Anyway, I also just got the Reader today and I feel it's great. I like that it is light and portable. I live in NYC so I commute to work by subway and I was really tired of trying to hold myself steady while trying to turn pages on the book. My arms used to hurt especially because I usually carry a messenger back on my shoulder that is usually loaded with "junk" that I carry around.
The only thing that I would comment so far is that I wish Sony would have chosen a different design instead of placing those dummy memory card things. I think that even if you leave those dummy cards in place, dirt or moisture can still get in. I owe a Sony digital camera so I know Sony can come up with something better!
