FWIW: I just now got a follow up email from Best Buy - the Pencil (that they said would be delivered Tuesday) now says it's backordered and could be delivered sometime between December 3 -15th. I cancelled and I'm back to just waiting for Apple to ship mine.
I tried cancelling my order but they wouldn't let me. Said that if you don't cancel within 30 minutes of placing the order you were stuck. They also said that mine was already boxed up and ready to ship. That was yesterday morning, nothing has changed in the order since. I found one in the store and yet they won't let me cancel the damn thing.
