I ordered a fully loaded BTO 27" iMac on December 1st in the afternoon. It's still processing, and has a Dec 31 - Jan 7 delivery window with free 2-3 day shipping.
Maybe. We all are. We're all tired of waiting. You won't be bothered as soon as you have your mac.
And for the time being we all are trying to speculate and think of when we'll be able to stop coming here and actually do things with our iMacs.
