ARC to me is scary... I got over the huge learning curve, and the nuances of autoreleasing, and retaining, and it seems like now I gotta unlearn all of that??? And not to mention some third party libraries/source code don't support ARC. To me, I'm gonna hold off using ARC as long as possible.
Well, you don't have to "unlearn" it. It's actually a good thing you went through the "pain" of learning it pre-ARC because if you understand how reference counting actually works, you will be able to make better and more informed decisions on the management of your objects in 5.0+ with ARC (e.g. when to use strong vs. weak properties). There's nothing magical about it, and Ray Wanderlich has a fantastic ARC tutorial that helped me greatly: http://www.raywenderlich.com/5677/beginning-arc-in-ios-5-par...
Holding off on ARC is only advantageous if you need to support iOS versions before 5.0, but ARC is the future of iOS.
