The issue here, for several of us, is that Apple advertised 2-3 day shipping, and we paid for it. Then, Apple shipped our purchases through a FedEx service that FedEx advertises as having delivery times between 3-6 days! In my case, I made a reasonable assumption that laptop would arrive no more than a day later than Apple's most conservative estimate. Since I'm leaving town after that, I'm pretty screwed by this development.
The people at Apple have been very nice, and I know they're doing everything they can, but it's still kind of lame.
