And I'm going to reiterate the reality of what happens when you buy a premium product: You are supposed to get some serious customer care. None of these were prepped from day zero, and Apple should have done a better job communicating that.
Couple that with reports of faulty taptic engines, annoying e-mails of "it's here!", and radio silence that's just unacceptable.
Many folks who are not used to that level of care generally are ok with just saying "oh it's whatever, they don't owe anything".
That, if you haven't figured this out yet, is not acceptable at this price point.
I buy premium stuff all the time and your points area all moot. Apple gave you a delivery window. One that you knew when you ordered, and accepted by furnishing funds to still buy one. Bitching they don't hold your hand every week to tell you it's not coming early is purely narcissistic stupidity.
