Re: not a Delivery?
Experience has shown that a large number of people in the queue are buying to immediately sell for a profit, and we now see that many are paid to be in the queue - and managed by people who are ready to get them out of the country and sold in markets where the iPhone/iPad is yet to go on sale.
It will be the same in Regent Street and Covent Garden etc this year, and for the last few releases as least you can walk further along Oxford Street and into a Curry's to buy one without any queues or fuss (well, bar being asked about the extended warranty). I am talking more about the iPad, but assume there will be stock of the iPhone in other places without the need to queue.
But if you do queue up, when the doors open you're treated like a God. Loads of people bowing down to you, clapping and making you feel so special as you hand over your credit card, get given a box and quickly booted out the exit.
Stupid as the whole thing is, I'll never forget when Nokia had its store over the road and launched a phone on the same day and there was not only no queue, but the shop didn't even open on time. Can't even remember what phone it was, but I vaguely recall it being the N97.
