ARC is not really 'needed' for anything, it's just a very nice way to prevent memory leaks and pruning lots of retain/release statements from your code.

I would not re-factor existing code without ARC if it was properly debugged for memory leaks and working perfectly, but for all new projects I have it enabled.

Sorry, I meant that I'm unconvinced ARC is nice, not that I'm unconvinced it's not necessary; it clearly isn't.
