Barnes and Noble's ebook reader, the Nook Color, has been rooted. Because the Nook runs Android it's not very difficult to root. The root essentially turns the Nook into a tablet and as you can see from the photo, it can run Angry Birds. If the development community stands behind the Nook you'll be seeing a lot more action for the Nook.

Check out the source link below for the instructions, but be careful because you could brick your ereader.
