Now - the $100,000 question is whether they are going to deliver in order - or put these things in a warehouse somewhere and make us all wait until next Friday. I would bet it's the latter.
My payment was initially rejected by Amex as a possible fraud entry. Has to do with internet orders, I was told. It was resolved quickly, but in the meantime I got an email from Apple saying the charge had been declined and that I had until a week from yesterday to post a different credit card before they would cancel the order. The point is that they will still be processing credit adjustments up until next Wednesday. So I would guess Thursday is the day of shipping for Friday delivery.
