Rooting e-ink Nook

Did you know you can root a Nook (e-ink) ereader so it becomes an Android Tablet? I sure didn’t. I guess most games won't run well on it, but there's bound to be some interesting options which open up, like first of all several different e-reading applications one can use. And Instapaper (or Readability) -compatible apps, making it easy to send web articles to the Nook to be read in clear formatting.
