Yeah thats fair. I'm starting my 3rd week of waiting now. I got charged last Friday for the price of the computer, and I'm still in the processing stage. I imagine once I get to the end of the 3rd week I'm going to start getting miffed if I don't see any movement.
I think most people are having theirs shipped to them by the first quoted week (e.g. If you were given 3-4 weeks, then it would definitely ship by the 3rd week). I guess I'm just unlucky because my 3rd week has come and gone and it's still in the processing stage.
