Now, I love the NOOK. After I changed it to an Android System. Bought "AndroidForNook 32GB Jelly Bean Dual-Boot". Tons of free Apps now! You can buy 8 ~ 16 ~ 32 GB cards for the change. And, you download "Nook for Android" (through Google Play) then you have all the books, etc... that you purchased on NOOK!!  It's the best of both worlds, then. Just do it - It's so much better!!
