I wonder why rolling for stats is so important to us DnD players. In storyteller, I pick exactly the stats I want. In Mutants & Masterminds, same deal. I decide what you want to do and your character is as effective as you want them to be. This does not work for a lot of DnD players I've met, and I wonder why.
I admit, it took my about five years to get into point buy. Now I'll never go back, but before I was very resistant. Rolling those stats was really important to me. Part of it was a way to differentiat myself from other characters. "Yeah, I'm playing a Fighter, but I got an 18 Con, where as Joe over here only has a 13." Another part was the chance of excellent luck, with lots of good stats that you couldn't otherwise get.
Now I prefer point-buy because it levels the mechanical playing field and forces players to think about their characters beyond mechanical stats.
This is probably a tangential discussion, but it's popped up a few times here, and the idea interests me.
