I stood the line at the Apple Store in Nashville on Friday and got exactly what I wanted - 2 iPads. During the 3.5 hours that I waited before launch at 5, I chatted and joked with folks in line around me, discussed what models we were getting, etc. Also talked and joked with the Apple store employees as they made their rounds. All in all, it was a great "Launch Day Line" experience for me because I and the folks around me made it that way, and the Apple employees seemed to have the situation well in hand. It worked out well for all of us.
I'd wager that it would have been a completely different experience had you been in line around me, OP. I am sure you were a joy to be around in whatever line you were in. Make suggestions all you want but, as one poster already pointed out, no two releases are handled the same - so many factors come to bear, and not all of them are predictable.
As I said, I bought two that day - one for me and another for my wife. If you'd been there and given me grief about buying my wife, who doesn't have paid time off to use like I did, an iPad...well, I would've been...cross. That's likely the best way to put it in a public forum.
Moral: be there early, be ready for the possibility that things might not go your way and make the most of the experience. And as my brother is fond of saying: "Acknowledge, move on and don't whine about it"
