First learn about modifying the nook tablet.  You can buy or create yourself a sd card with a custom ROM on it. Doing this lets you bypass the BN OS because the nook looks at the sd card first when booting up, it also keeps the nook OS stock and BN can do all the firmware updates they want to do without affecting the SD Card ROM.  With a custom ROM you can install apps or read ebooks not offered by BN i. e. kindle books. I love my NT and learned to make it do more than be an ereader, yet still have a stock ereader by swapping to a blank sd card. Let your Nook Tablet be an Android Tablet without the restrictions of BN's poor customer service. I'm as computer knowledgeable as a rock and was able to learn how to do this in about 4 hours of reading google.  Just google.  nook tablet xda
