Thanks for that link, I missed that thread! Hoping it'll be as simple process at my local store...
It probably will be. MOST Apple Stores are well-adapted to crowd control.

I have only read of a few clusterf***s here or there. Otherwise, it is usually a very civilized process.
Even though I have a lot of experience with Apple Stores, the other day was the first time I ever stood in line for a product and the first time I ever went through the "ticket" process. I waited a couple of months to get my first 2 iphones (after the furor died down); was one of the lucky ones who got to order my iPhone 4 online (which they delivered the day before launch day last year); and waited a couple of months initially to get my iPad 1. I couldn't wait any longer to get my iPad 2, and figured I would just stop at the store on my way to the gym.
Frankly, I am really happy they handed out the tickets...and even before they did, the personnel treated me very well. When I got there after 0600, the only people in the store were security guards, cleaning personnel and a couple of employees. Even the security guard was awesome, coming out to check on me, and to tell me about the process they follow once they begin handing out tickets.
All in all, a VERY positive experience...and this is from a person that HATES waiting in line and will avoid them at all cost.
Hope your experience goes as smoothly. I am sure it will.
