N2A Cards (R) - Transform your Nook Tablet into a Kit-Kat 4.4.2 Android Tablet (new 2014 version) - (16 GB)
This is a great tool for making a Nook more user friendly.  I really liked that the Nook App was already loaded and that I didn't have to reboot just to access my books.  Also gives me the ability to transfer some of my magazine subscriptions to my nook through the publisher's tools rather than having to cancel with the publisher and resubscribe through Nook.
