title: Should I use ARC in objective-c?
body: <p>Looking at the release notes of OS 10.7, there's some stuff about using Automatic Reference counting (ARC) to make memory management simple. I'm about to embark on a new Cocoa project soon and wondered whether it would be worth using the model (the way I understand it, you can't mix between using ARC and not using it)?</p>
  
  <p>The dilemma seems to be using something new versus using something that could potentially save lots of debugging time later. But is that the case? Has anyone played around with it and found no real-world benefit?</p>
