Some of my colleagues did some perf testing for mobile and found Angular.js was not suitable (I guess due to the compilation it does). I don't have any numbers unfortunately, but I think we use mostly Backbone for mobile projects here.
Thanks for the tip. Would be interested in stats. It's such a timesink to evaluate any of this new stuff. There's clearly a market for a tomshardware.com equivalent for frameworks and software stacks.
