Once again, I would like to point out that this week Apple U.S. store changed the terminology for order status. "Processing Order," is the new term for "open."
I find it very strange that Apple has already shipped Tiger to someone. We'll going to have to see, if anyone else reports this today. I just don't see it happening. For example, I didn't pay for shipping, and they have my order at 2-day air, so I'm sure they aren't going to want to send it out until just a couple days before the 29th. Unless they decided to save on shipping and they are shipping some of the orders via ground, a week early, and if you live close to the starting point you'll get it quite a bit early.
