If you have a Nook Color from Barnes & Noble and would like it to be an Android tablet instead, buy a microSD card and follow along. Easy peasy, and w00t!

The great thing about this method is that the non-standard software is on the card. Take it out and you turn on a regular old Nook Color. No warranty voiding.

Way cool.
