Shipped "today", these apparently being the first shipments out, means they're shipping Friday evening China time, which is Friday morning US time (they're 12 hours ahead of EDT.) So since people are just getting shipping confirmations, they are shipping Friday, even if you got it late Thursday US time...
Since I love speculating, and the one report so far is out of Shanghai, I'm now guessing they'll be on FDX28.Leaves Shanghai ~9PM local time, which is 9AM EDT. Not listed as having operated last Friday, although it did the Friday before that, so it could be a different flight, but the timing would be similar to connect to continental US-bound flights from Anchorage... which could get those MacBook Pros to most people on Saturday if Apple wanted them to!
Dude....your awesome...lol. I'm totally calling them in the morning and telling them what you just said....I wanna see what they say, hahaha.
