I'm going all in on Angular, even building a big open source project around it (http://ionicframework.com/). What really drew me in was hearing from developers that were using it at big, slow companies for entire teams building production apps.

Officially adopting a technology like that is pretty rare, and I guessed Angular had started to achieve a level of adoption that would make it the most worthwhile to invest in.

I also wrote more about how I think it's going to be huge, which I admit sounds best if you already love angular :) http://ionicframework.com/blog/angularjs-will-be-huge/
