I am not sure if this has been brought out, but I would like to make a knowledable comparison, and see how far we go; The differences between the Kindle and Nook, as I see them follow: Kindle Large selection of books(throgh Amazon only) Long battry life due to Black and White only No google or sideloading Battery replacement but no SD card upgrade Let me know what I have missed! Present update is 2.5 Nook
Large selection of books, Google EPub and library, plus loaning of books Complete battery replacement and SD card replacement up to 16 Mg- Simply take ooff back cover, everything is right there. Good battery life due to color; which lessens the battery somewhat Other things to consider;your location On a 3G model, like a cell phone you have access, having WiFi gives you more speed Let me know what I missed The Nook, DID NOT QUICKLY provide software updates, we had freezing of the unit, lack of responsive updates, and not so good page turning and speed. Most of these issues have been fixed, with update 1.4 The model which I did not mention was the Sony personal Edition; this has the least selection of books etc, but has a replaceable battery and SD card expandble to 32; it uses AT+T 3G Let me know how I did and what I missed!
