Some folks over at our sister-site, TabletRoms.com, created a great video to share an easy new root method for the Nook Tablet. This new method does not require a PC, and instead uses an SD card, and some simple steps along with a few files. The original source of the method was XDA forum member, Indirect. The video gives a great walk-through, and if you want more info, and the files necessary to perform the "rootery", you can find it at the source link below.
