We us Ember at my company. We started using it around the 1.0 release. We have been very happy with it. But as a shop that doesn't really have any dedicated front end developers the most frustrating thing for us is that their conventions are always changing or worse threatening to change but don't so your left always wondering if what you are doing is the right thing. People have been waiting for controllers to be deprecated for years. That being said I think they do have to make these changes to keep the framework moving forward and I appreciate the amount of effort they put in to keep things backward compatible. I think now that they are providing code mods for a lot of the new conventions people won't be as hesitant to upgrade. Before there was a lot of friction when upgrading to a new version that had different conventions and you felt you should go and modify your existing code to follow the new conventions. I have confidence that with their strong user base they will stay relevant for many types of applications. If people are hesitant to try it I'd tell them to keep in mind that even though Ember has conventions and provides the ember way of doing things it is possible to integrate most of the exciting things going on in the js world with Ember. Some people even use react components in their ember apps.
