For Nook device users, here is some good news from N2A Cards: they can now be made to run the latest Android KitKat in both downloadable form or preloaded micro SD card. This applies to the entire Nook tablet lineup, which includes the Nook Color, Nook Tablet, Nook HD, and Nook HD+. Also, an inherent benefit of installing Android KitKat via N2A Card is that users will have the option to dual boot their Nook devices with the stock B&N software that the devices come pre-loaded with.
As for the price, the micro SD cards pre-loaded with Android Kitkat can be ordered from the company site for $30, or can be downloaded directly for only $20. The deal is sweetest for those who have dealt with N2A Cards before, as they need to pay just $10.
Overall, this is an easy option to explore Android KitKat on Nook devices, with the liberty to come back to the default B&N software installation as needed.
