For the project I'm working on, whenever I would bind to a 'click' event (via jQuery.on or a Backbone event hash), I instead just pass in a variable that's set to either 'click' or 'touchend' based on touch support detection done on pageload. If the element is within a scrollable area there's a little bit of extra logic needed to get everything to work happily (so it doesn't fire the event handler if you stop scrolling with your finger on the element). In that circumstance you'd probably better off grabbing one of the many libraries people have written to take care of this, but if that's not a concern (and it isn't in my case, since the parts of the app that shouldn't have the 300ms delay don't scroll), the advantage of this is that the only logic it requires is the touch detection code.
