Pre-Order vs Reservations I spoke to Apple customer service today (Thur, 3/11) @ 1-800-MY-APPLE. They told me that there is no difference in delivery/availability between Pre-Order and Store Reservations. If you Pre-Order, the WiFi units will be delivered (not shipped, but delivered) to you on April 3rd. They also indicated that you could also pre-order the 3G models tomorrow and they would be delivered in "late April". I am thinking that Pre-Order may be a safer bet for delivery than a Store reservation. I suspect that each store will be shipped "x" amount of product based on previous market activity. Obviously there could be a chance that any specific model may sell-out. And with pre-order, you avoid the crowds.
