I've worked on 2 production Ember apps. The first was a nightmare because there were 2 way bindings and the team that built it didn't know how to use the router. The second was a dream because we built it after a couple of years dealign with the fallout from a bad ember app (plus "data down - actions up" was now the prescription). Ember can be really nice if you follow the happy path.
