It was bound to happen eventually, and in typical xda-developers style, it came sooner rather than later. There are 50 pages worth of posts at that link, but what they all boil down to is that Barnes & Noble’s NOOKcolor (unboxing, review) has been rooted.
I think I’ll wait to take the plunge myself until I see some real benefit…or until I get sick of being hounded to do it on video (that’s not an invitation, though I appreciate the interest). For now, it’s enough for me to know that it’s possible to run Angry Birds on my e-reader, or to spiff it up with LauncherPro. Nice.
