I can't really answer this poll. I ordered mine CTO 1.6GHz / 4GB RAM 11.6" from the Apple Store online Saturday 10/23 at 2:30 PDT. I opted for 2-3 day delivery. Item was shipped today 10/27, Expected delivery Monday November 1st by 10:30am (estimate said delivery Oct 27 - Nov 2nd), Ships 1-3 days, 2-3 day delivery. If they deliver my MacBook Air on November 1st, it will have taken them NINE DAYS from order to delivery. Two weekends and a full week. So, I can't answer your poll. Yes, it will probably come within the "expected delivery date" but 9 days is way more than 1-3 days to build and 2-3 days to ship.
But, I may get lucky and get mine by Friday. Now that would *really* lucky, right?
