Well, phooey, I don't see an answer to the question, and I've tried mounting and unmounting the Kindle in all sorts of ways. However, I do have a wall charger plugged in right next to my desk (same one for my cell phone), and if I ever want to read and charge at the same time, I can do it with that.
And yes, E-ink rocks! Other devices can provide e-book reading, but there is only one Kindle. If I was a rich guy, I would probably have a rooted Nook, too, but I'm happy with what I have in any case.
