title: To ARC or not to ARC? What are the pros and cons?
body: <p>I've yet to use ARC, since the majority of the code in the project I'm working on at the moment was written pre-iOS 5.0. </p>
  
  <p>I was just wondering, does the convenience of not retaining/releasing manually (and presumably more reliable code that comes as a result?) outweigh any 'cost' of using ARC?
  What are your experiences of ARC, and would you recommend it?</p>
  
  <p>So:</p>
  
  <ul>
  <li>How much benefit can ARC bring to a project?</li>
  <li>Does ARC have a cost like garbage collection in Java?</li>
  <li>Have you been using ARC and if so, how have you found it so far?</li>
  </ul>
