I got mine today, two whole days ahead of schedule. My original delivery date was March 5, then I called Apple to switch my antiglare option to glossy, and that made my release window March 5-11. When it shipped, FedEx's estimated delivery date was March 4, a full day ahead of Apple's. Then today, the 3rd, at 11am, it came, a full 48 hours ahead of schedule!
I bet you can imagine how pleased I am!
I'm also going on a trip for spring break and leaving the afternoon of the 5th. I was so worried it would come after I left and I wouldn't get to see it. Looks like thats not a problem anymore!
On top of that, my Mini DisplayPort to DVI adapter doesn't quite fit my Cintiq display, which was a real bummer. I called Apple up asking for an exchange, stating I'd pay the difference, but since I ordered the adapters with the computer they couldn't exchange them. So instead, the customer service rep just sent me a dual-link DVI adapter for free!
This has probably been one of my best experiences ever. I'm really thrilled haha!
