IMHO, it's hard for these client side frameworks to get much steam in Angular's wake.. Though Thorax is much easier to start, I think over time Angular's power will make it the dominant front end framework out there
That's exactly why we chose Backbone over Angular earlier this year.
An imperfect analogy, but: maybe Angular is like Wave, Backbone like Email...
If you pick Backbone, you'll be inventing a lot of patterns yourself and scaling it, but I think that appeals to a lot of people.
It might be all beautiful when done right for big projects for what I know. But then the examples on the angularjs site are giving the wrong impression.
