Yup. I don't think it's any coincidence that the only really prominent place where ARC is being used is iOS. It's a platform where reference counting was already in place, where you can have a reasonable hope that most the programs are too small and simple to take much of a hit on the overhead, and where memory leaks can't get too far out of hand because the OS reserves the right to kill processes whenever it wants.
