I ordered mine on 2/23, scheduled to ship on 3/23. delivery date of 3/30.
I e-mailed Apple a couple of times to whine about the delay, and they said they'd give me expedited shipping when it was ready.
On 3/14, I received notification it was shipped with a scheduled delivery date of 3/17. I started tracking the FedEx number. It left China on 3/14, arrived in Alaska on 3/14, and was IN MY HANDS on 3/15.
This still blows my mind. It took my fiance 8 days to get a check mailed from Minnesota to Indianapolis and I got a computer from China, via Anchorage, in less than 36 hours.
