Aren't sideloaded books still available, or did B&N wipe those too? Hmmm, if B&N is going to peridically wipe the NCs connected to WiFi then methinks they will have a mass revolt on their hands.

Hey maybe the NCs are revolting against that terrible 1.2! Perhaps they are puking it out of their system. Sorry, I couldn't resist. Oh well, as far as I'm concerned the WiFi is rather useless on the NC anyway, so it is probably better to leave it off to keep B&N from piddling with or on your NC.
