How many books do you store in your reader?
I have a K3, not much memory onboard. It doesn't matter though, because I found that keeping too many books in the device is detrimental to focused reading.
I just don't have the discipline. I couldn't read on the ipad because I would keep getting distracted and go play a game or surf the net. Same thing with the Kindle, I get distracted in a boring passage and switch to another book. This is especially true for non-fiction books, I don't have a problem sticking to fiction usually when the story is exciting.
I think I'm going to just leave one or two books in the kindle for now. Anyone else does this?
