I would say though, that having been using Objective C productively for over 10 years now, that I still find ARC something I have not needed. So far. I'm kinda hoping that remains true, because it actually seems pretty complicated in order to cover all the arcane use-cases and I'd rather stick to what I know which has the overwhelming advantage of being really, really simple.

Myself, I’m becoming a fan of ARC just for the performance benefits. Particularly once the frameworks get converted to ARC, it’s going to result in a lot fewer autoreleased objects being created, which will not only cut down on overhead but also make Dave’s statement about not needing to worry about autorelease pools much closer to being true (in general, I find that users tend to get upset if your app grabs huge chunks of memory when it doesn’t need to, even if performance is good).
