Yep, you are lucky. I got up at 2:30 Eastern to be ready. I had my iMac up and ready, with my watch marked as a favorite, and my iPad by my side running the Apple Store App as a backup. At 3:01, the site wouldn't work for me at all, and neither would the app. I felt "lucky" to get my order placed at 3:08, and even so my black SS has a generic ship date of "June," without even a day range. Clearly there never were any available for launch day. A few people did somehow manage to get May dates. They are the lucky ones.
Everything is relative, my friend!
It was nice to see your post! Makes me feel a little better about getting that May 13 - May 27 delivery window. As my mother used to say, about circumstances, it could always be worse.
