Those of you with a nook color can turn it into an android tablet (sans cameras, of course) very easily with a n2a card. The Nook Color has a slot for micro SD memory cards. The n2a (Nook to Android) card fits into this slot. Follow the super easy instructions and you will have an android tablet in minutes.
Once you have done this you may run your NC using either the original Nook operating system or the Android system. Load in the apps from the Amazon, Android, or other app stores (not Apple/iPad apps) and away you go. You can use reader apps from Nook, Kindle, Kobo, or any of the independent reader apps, some of which are considered better than the N, K, or K readers.
You can also use better e-mail and browser apps such as Dolphin, Opera, Firefox, Chrome, etc.
