Interesting. Did the other watches indicate an immediate shipment on April 24th when pre-ordering from Apple? I would have been surprised if Apple indicated that a Sport Watch with WSB would be shipped immediately on day one (although this is the watch that my wife received on April 24th). I didn't ignore the delivery time quoted, I just accepted it as a "normal" Apple lead time to ship watches. At the moment, at 3:00am, I wasn't thinking of browsing several other watches to see if the shipping time was better or worse. I was more concerned about getting my order placed. I have no regrets. I was more interested in what information was available, from Apple, on the pre-order website.
Other watches did indicate shipping windows beginning on April 24. That being said, I think a lot people's experiences were similar to yours. They were not concerned with the checking the shipping time because they were simply trying to get their order placed ASAP, which is understandable.
I think Apple could have provided better customer service by letting folks know--prior to the start of preorders--that certain models would not be available on April 24. I don't think that is inflammatory - but similar comments by me and others tend to be met with a lot of animosity and condescending responses. I don't think it's an unfair criticism, but it really irks some folks here. I think that is why you received such a terse response to your initial question.
