Most of us are familiar with Barnes & Nobles’ Android Nook e-reader, but what if you thought to yourself, “If only I could make this into a full tablet, that’d be great!” As it turns out there might a solution for you with the Nook2Android. Basically the Nook2Android is a microSD card that comes loaded with Android’s Gingerbread 2.3 operating system, and following the instructions at the Nook2Android website, you will be able to dual-boot your Nook into an e-reader or into a full fledged Android tablet.
Removing the microSD card will return your Nook back to what it was before, so there’s no worries about ruining your beloved Android e-reader. For $35 it seems like a pretty inexpensive way to get an e-reader and a tablet all in one.
