I'm a federal employee. Probably similar in some regards, in some peoples' eyes (no offense intended).
Yeah, I don't have stuff that must be signed for delivered to my house any more. I realized today that Thursday is the day we fly off for a long weekend to attend my nephew's high school graduation. I'm sure Apple planned the computer's delivery to coincide with my departure.
Just hope the store doesn't send it back or sell it to someone else before I can pick it up next Tuesday.
You should call them just to make sure they keep it.
I'd try to bring it along. It would be so cool to be able to test out the size of the new rMB on an airline tray.
