title: Unique features of Vim over more "modern" text editors like Sublime?
body: <p>I'm working on a presentation about vi/Vim. I'd like to highlight some of the features that they have over newer editors, especially Sublime Text. Many of the differences can be equalized by adding plugins, but here's my current list of out-of-the-box functionality that appears to be unique to vi/Vim:</p>
  
  <ul>
  <li>vi is available on the vast majority of Unix machines, including servers</li>
  <li>ports are available for just about every operating system, including mobile</li>
  <li><a href="http://vimdoc.sourceforge.net/htmldoc/visual.html#CTRL-V" rel="nofollow">blockwise-visual</a> editing</li>
  <li>diff viewer built in</li>
  <li>spell checking built in</li>
  <li>multiple registers (a.k.a. "clipboards")</li>
  <li>Vim is free software, open source, charityware</li>
  </ul>
  
  <p>Are there any other unique built-in features I'm overlooking?</p>
