Of course not. I would go with a competitor. Would it be what I want? Probably not. Would I deal with what I can get? Sure, I wouldn't have any other choice. If I was to do more than that I would take it up with Google, and not an unaffiliated website.And I shouldn't because? If you and your neighbours ordered Google Fiber, with a 2019 promised date. Yet their houses are now all hooked-up and you still got the 2019 date, would you just sit there?
If you think the logistics are what you describe, I have bad news for you.I have some idea. I live in Hong Kong. 1 hour drive away from Shenzhen factories across the border. They can build the iPhone, pack it and deliver it to the apple stores here in less than 3 days.
If you thought an Apple watch takes more than a day to be built, I have bad news for you.
Keep in mind you are but a single order in a million. Given what you ordered, I think chances are higher that Apple seeks to build more units of another model than what you ordered. Does Apple make the one happy or the many?
