title: MonoTouch - XIB or not to XIB?
body: <p>I am deciding on where using .xib files are needed while developing with MonoTouch.</p>
  
  <p>My current project needs to work with iPhone and iPad, so I'm wondering if even using Interface Builder is worth it.  I already have to remove some designer files so that 2 different views (one for each device) go to the same controller.  I also am the only one working on this, and there will be no designer working in IB.</p>
  
  <p>Here are a couple questions:</p>
  
  <ul>
  <li>Is there any performance benefit/decrease to using XIBs?</li>
  <li>Is there any software design issues, detracting from MVC, etc. that one way or the other will inihibit?</li>
  <li>Is there any versatility drawbacks to using XIBs, like is it tough to implement lazy-loading for certain views with XIBs?</li>
  </ul>
  
  <p>Thoughts?</p>
