N2A Cards (R) - Transform your Nook Color into a Kit-Kat 4.4.2 Android Tablet (new 2014 version) - (8 GB)
This is absolutely amazing. Inserted the SD card into my Nook Color and it booted right up as an android tablet. Beautiful home screen with five home pages. It comes preloaded with things like Facebook, Pandora, Gmail, Angrybirds and the Nook Reader app. If you find you can't read your comic books, magazines, etc., just update the nook reader!
