I just got back from the Apple store and the sales guy said this: 1. They stopped taking pre-orders yesterday and if you didn't order one, good luck in getting one. 2. They have hundreds of pre-orders. 3. No one can just walk in to buy other products and bypass the line. 4. They will have all the accessories available, including the iPad dock. 5. They will hold all pre orders until the line is gone or 3PM; whichever is longer. 6. This launch won't be like the iPhone launch because everyone will be standing in a queue/line. The sales person will get the first person in line, help them get whatever they want, ring them up and then help the next person in line. So the only people in the store are the ones the sales people are helping from the line. No one can just walk into the store until the salesperson gets them.
