The thing I love about Backbone is it gives you true freedom of how to think about your application. I think everyone should build at least one rich client web app with Backbone before making any decision about using Angular or Ember or whatever. The reason being that those frameworks are written by very smart people who have chosen particular approaches based on their experience. If you are a bit inexperienced it's easy to be indoctrinated into their worldview and begin to think of it as the one true way when in reality you are just cargo-culting on decisions that are not applicable everywhere. I suppose one could make the argument about any framework or library at any level of abstraction, but it seems particularly important in the javascript world because the problems just aren't understood all that well yet, and churn is very high.
