Look for the existence of touch, if it is not present then you are more than likely dealing with a desktop:

edit: my original try/catch approach was apparently deprecated ( https://stackoverflow.com/a/4819886/1026459 )

$(document).ready(function() {
 var isDesktop = (function() {
  return !('ontouchstart' in window) // works on most browsers 
  || !('onmsgesturechange' in window); // works on ie10
 })();
 //edit, if you want to use this variable outside of this closure, or later use this:
 window.isDesktop = isDesktop;
 if( isDesktop ){ /* desktop things */ }
});
