I ordered. It was a horrible experience, even being on the site from 11:00am EST until 12:00pm EST, when it was supposed to happen. 11:59am hit and the site immediately went down on my end, whereas previously hitting refresh took only about 3 seconds, the site no longer came up at all. I laughed and continued my luck. Got in around 12:09pm when the grey was actually listed as in stock (it wasn't around 12:05, only black), and then entered credentials. Got all the way to the very last button submitting payment, and the site was stuck on a forever loading spinning circle...I waited quite some time before it loaded a "Gateway error: timeout" type error. Tried again, happened again, tried again, can't even enter site...it was horrible.
I've now learned maybe it's NOT a good idea to be first with these things--perhaps just waiting until about fifteen minutes later would have helped. Not sure. Finally got it after about 1pm, an hour later than when I attempted. I entered my card info so many times I have it memorized now.
