Disclosure: I'm rebuilding a pretty big BackboneJS app (which I started building two years ago with a team that grew to two dozen people) into an AngularJS-based mobile webapp.
Note also that AngularJS is a whopping 700 KB before minification and gzipping (270 KB minified/gzipped).
Here is the file http://code.angularjs.org/1.2.14/angular.min.js And here you can get the gzipped size http://closure-compiler.appspot.com/home
