I ordered my iPad on May 5th, and just got shipment notice this morning. Per FedEx tracking it was picked up in SHENZHEN CN, and delivery should be on the 20th.
I know what you mean mbradeis, the wait is killing me 2! The last status i got on the apple site said "prepared for shipment" and then the site went down for maintenance so i can't even tell if it shipped yet or not. arrrrgh. lol.
