I have a Kindle 3G and Wi-Fi - bought it in July - love it. I like the long battery life. I don't mind the black and white screen at all. I was reading about the Kindle Fire and it seems like with all of the bells and whistles that it would spend a good amount of time on a charger. Love mine and I have already read so many books and just started experimenting with the Library (have 2 library books so far) and it works out great!
