So what performance issues were encountered when converting backbone.js to ember.js? Why isn't that an important factor? How difficult is it to overcome the inherit drawbacks of a simple framework? I'd say personally that behind simplicity, performance is the most important factor for an app (JS-enhanced sites may benefit far less). The challenges that I've seen while using backbone mostly consist of unifying the views, models, collections, and helper objects (or for lack of a better term "Services") together. So far some of that overhead involves adding a "_super" function and abstracting out instantiation so that it is sane. I'll write up about the experience afterwards, but backbone.js is a pleasant treat after leaving JMVC.
