title: Lightweight UI Framework for JS/HTML5 Webkit-based mobile development with decent list performance
body: <p>My question is slightly different from <a href="https://stackoverflow.com/questions/6252014/looking-for-a-recommendation-for-a-lightweight-mobile-html5-javascript-framework">Looking for a recommendation for a lightweight mobile HTML5/JavaScript framework</a></p>
  
  <p>I'm joining a JS/HTML5 project that is targeting the ipad, currently using Backbone.js for MVC and Zepto for dom manipulation. They've experimented with jQuery mobile and found the list performance to be underwhelming. </p>
  
  <p>Basically I'm looking for an alternative mobile Javascript UI framework with a non-viral OS license (Sencha seems out with gpl 3, and I'd like something focused purely on ui widgets), which provides performant dynamic lists and a general set of iOS style ui widgets. I do have experience with enyo, but I don't particularly like it, so that's out of the question as well.</p>
  
  <p>Any suggestions? </p>
