You're correct. The original dates were listed as 10/4 - 10/10. But none of us changed the target delivery dates to 9/21, 9/22 or 9/23. Apple and UPS did. They updated the expectations, and people are reacting to the "failure to deliver" on the new dates that Apple/UPS provided. Not arguing with you, merely giving some context to the frustrations that are being expressed here.
As I stated earlier, the 10/4-10 dates are fine, as far as they go. And if Apple/UPS is going to meet them, fine. But don't raise the expectations by providing newer/earlier dates and then not deliver.
