My children and I read a lot, and they kept wanting to borrow my Kindle, so I passed my down K1 to them and got a K2 for myself. Now they fight over the K1, so I want to get a 3rd reader. That should be enough for now until my next one in line gets a little older.
I'd like to get a Sony this time because I'd like a reader that reads different formats, and because I won't have to convert library ebooks to work on it like I do for my Kindles. I may hold out to see that the new iRex 800 is like. If not, I'm going to try out the 600 and see how we like it.
