No, but I'm also interested in this. I've been looking at Ember.js / Backbone.js / Angular.js for a new cross-platform mobile project and leaning towards Angular.
I had meant to do the same with Ember.js as well but AngularJS did the job so well that I decided to just go with it. So possibly Ember.js is even better. I don't know. But I can say we haven't really regretted AngularJS yet.
