My question is slightly different from Looking for a recommendation for a lightweight mobile HTML5/JavaScript framework
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.
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.
Any suggestions?
