title: NSMutableArray, alloc or capacity?
body: <p>Is there any reason to go with either of these, other than one returning an autoreleased object and the other needing a manual release?</p>
  
  <pre><code>NSMutableDictionary *drink = [[NSMutableDictionary alloc] init];
  // do things ...
  [drink release];
  </code></pre>
  
  <p>OR</p>
  
  <pre><code>NSMutableDictionary *drink = [NSMutableDictionary dictionaryWithCapacity:10];
  </code></pre>
