title: ('ontouchstart' in window) returns true but no touch events
body: <p>I am trying to write code that will run either in a browser or as a phonegap application.
  One of the things I need to do is to decide if I am in an environment that supports touch events or not.</p>
  <p>My current problem is that my Chrome (20.0.01132.47 m) returns <code>true</code> for <code>('ontouchstart' in window)</code> but it does not fire the touch events.</p>
  <p>When I open the Developer tools settings dialog (the gear icon on the bottom right of the Developer Tools). I get an option to &quot;Emulate touch events&quot;. When I check this option the browser fires the touch events. but when it is not checked it does not fire the events but the detection I use still says that the touch events are available.</p>
  <p>Can I tell from script if &quot;Emulate touch events&quot; is enabled or not?</p>
  <p>JQuery based answers are fine.</p>
