It would appear Apple is a wee bit perturbed
To Our Valued Apple Customer: Thank you for your recent purchase of the magical and revolutionary Apple iPad. We would like to advise you Saturday delivery is not available in your area. Your order will be delivered on Monday April 5th.
This does not apply to those who reserved for in-store pickup at one of the 3 Apple retail stores in Honolulu as UPS will be delivering those pallets to the store. Just residential deliveries will not be made by UPS primarily due to the tight shipping window specified by Apple and the early logistical decisions made by UPS with regards to the Hawaii batches of iPad’s shipped from China.
Customers in other parts of the US defined as rural by UPS also are receiving the same e-mail message.
It should be noted that Apple did mention about this possibility of a delayed delivery on their preorder page. What is probably annoying some customers though is that Apple normally ships via FedEx which has a pretty good track record of making Saturday delivery when a customer pays extra for that service. UPS is proving they are unable to do so even with Apple making arrangements with WorldEase. The next time Apple has a high profile preorder release such as this, they should specify which shipper they are using so that customers can make a better informed decision.
