Nook VS Kindle 2, help?

I can't give you too much information, but I will ask you this. What do you want your e-reader to do? I don't want mine to have aps, etc. If I wanted that I'd get an iPhone. What I want is to read on it and the kindle fills that need nicely. I've seen many people compare prices between Amazon, B&N, and Sony (the three prominent stores). Amazon always wins out. They're taking a loss on some books, though I think they're doing well enough honestly. I believe Sony reader offers to let you use library services, but they're dependent on the library in your area and how many copies of what books they have available. Obviously most libraries haven't jumped on this yet. As for the battery, I've had my kindle 9 months and not an issue yet obviously. I'm not seeing any problems so far. I wouldn't consider replacing the battery every so often so bad. I also figure the K1 HAD a user replacable battery and there's some reason they don't now.
