Not me, its totally useless........

Its just a way to centralize all leadership boards. Its kinda neat. Plus I expect a few more additions in future updates to make it a bit more worthwhile. But yes it isn't the best app on the iphone at the moment, that's for sure.
 
I open it up every now and then if I get bored enough and also if someone decides to add me to their "friends" list, but otherwise I don't really care about it. >.>
 
Right now Game Center is more for personal bragging rights than anything else. There's nothing social about it at all, which I think a lot of people were expecting when it was first announced.
 
It really screwed up my iTunes account. I have 2 iPhones that I was using to update, etc. with, and when Game Center came out, it only takes one email address per Game Center account. After changing one of the email addresses (not the primary) it switched, and the secondary became the primary.

I almost lost $25 I had from an iTunes gift card. ... No use for it now. Wish I hadn't set it up.
 
I have never used it. I think OpenFeint is superior.

I am the opposite. Although I don't love Game Center, I detest OpenFeint. Not for its capabilities, but for presentation (hideous UI) and fact that I must launch individual game then look OF button (which aren't always obvious) for to check achievements and leaderboard.
