I think many of these people do it for the experience, to be seen, and to "commune" with other Apple Acolytes. I'm not demeaning them, just saying...
oh please, most of them are not there for the right reason. i've seen scalpers' ads on multiple Chinese forums looking for people to line up, they get paid $400 per person if they can buy 2 iPhone 6+, $200 for iPhone 6.
This whole line up thing in Australia is a sham
