I am in love with my Nook color, especially with the Lend Me feature, I have borrowed a whole series from Eva already!
And really, the biggest thing seems to be the battery life. But tell me. Do you plug your cell phone in every night? Can't you plug in your eeader too? I can go a couple days without charging, but I plug it in every night out of habit. I will say it is a bit heavier than the Kindle. My BFF has a Kindle and adores it, there are things about hers I like and things about mine. Truthfully, I would advise playing with one of each if you know someone who has them. Otherwise, you just won't know. The Kindle is better for my BFF as it is more indestructible and she has a 4 yo who likes to get his hands on it. Anyway, Barnes and Noble has almost as many titles as Amazon, the prices are nearly identical, so I can't see it being an easy decision. I also like that my Nook is back lit. You have to have an independent light to read on the Kindle. Sorry if this is repetitive, I didn't read everyone's responses first, lol.
