mine still shows not shipped yet but when i called apple the recording says prepared for shipment. Wonder why the discrepancy ? also once it shows prepared for shipment how long before that actually ship? just checked they haven't even charged or authorized my credit card yet. I don't get this i ordered 10/28 and people in November got theirs
See my post here for my ordering experience (this far v good)

Basically ordered 8th Nov, shipped today (14th), UPS estimate delivery for 16th of Nov (Apple on or before 20th).
I think a few things affect the delivery:
1. I ordered extra RAM (8GB), but that doesn't seem to matter
2. I think Apple are sending a stream of products globally and not just concentrating on the US, so some people, maybe in different regions, might get their's quicker than others - if they did it solely on order date, you could be waiting a long time unless in the US
3. If systems are soak tested, or maybe final inspection (but maybe they are not with so few options), it could be that your order gets picked, it gets checked, a fault occurs and you have to go back into the queue or your build starts again. I know that Alienware operate this kind of system.
4. If you ordered other things like software, maybe a different team are doing these systems and this slows things down
5. Maybe peripherals like a printer or a different keyboard are causing holdups
Of course its all just speculation, but for me at least, within 36hrs of getting the 'Prepared for Shipment' notification on the US site, I've got a tracking number.
Fingers crossed yours starts to move along soon also.
