Also got the Apple e-mail stating Saturday delivery, but UPS still says delivery date unavailable and under services it still lists Express Saver and mentions nothing about Saturday delivery.
That said, it left Louisville at 5:43am, went to Birmingham (my state) and then left there at 6:31am, so it's moving very quickly and I assume is headed to my city. I'm a 4 hour drive from Birmingham, so it couldn't possibly get to my city until 10:30am... Wondering if that is too late to get on vehicle for delivery.
I have to say, even though UPS did a really poor job of communicating what was happening in Asia, if they pull off a delivery today, I will be more than a little impressed. Gotta wonder if Apple threatened to stop using them or what's got them scrambling.
