I just purchased a Nook Tablet. Moved over from the Kindle Fire because I didn't like how thick the screen was and thus how glossy / reflective it is. I actually don't mind the Nook interface. Literally all I want to do is run the Kindle App for Android along with Comixology. I have purchased significant content on both and I don't want to lose access to it. Otherwise I like the Nook and would be content to just use the stock OS. Is this possible? Or do I have to dual boot?
