I ordered the 42mm space grey sport watch (I guess I have very mainstream tastes) on opening day, with confirmation email posting at 9 minutes past the witching hour, for delivery in the US. No movement toward shipping yet. Initial shipping window in the email is May 13 - 27. I woke up at an ungodly hour to place the order because I assumed there would be supply issues. When news came out yesterday that some people were seeing orders ship earlier than their initial dates, I found my way to this forum to see what I could see.
Listen, I can be as all about instant gratification as the next person. I remember as a kid sending in cereal box tops for a Star Wars toy and then running down to the mailbox every day for a couple of months waiting for the thing to turn up. That said, I'm kind of amused at the folks who are getting worked up about all this and calling it a 'fail.'
Relax. This new watch is a whole new product category. There was no real way to predict demand, particularly when you consider the number of options available. If Apple made a mistake, it was in not taking Henry Ford's approach to the Model T. "Any customer can have a car painted any color that he wants so long as it is black." While Apple could count on a certain loyal customer base, there was also lots of online chatter about the Apple Watch from people saying they couldn't see the point in having the thing.
So you've ordered a popular product. From Apple's standpoint, it's better to have some antsy customers being impatient than to have exceeded demand in the initial manufacturing run. Can you imagine it? Even if they had five million first day orders (more than all other smart watches sold in a year), if they'd built 7 million, the news would be that sales didn't meet expectations, and their stock would plummet. It's crazy, but true.
So be patient. The new toys will all arrive soon enough.
