I like the idea of being able to use my own raw domain objects as the model, which in angular you are supposed to wrap up as a service as i understand it -- a bit of boilerplate i don't love. I'll definitely keep my eye on this project, it sounds like it has a nice architecture.

My last piece of advice is docs, docs, docs. Making a framework easy to learn by example is the key to adoption imo. That was one of the chief complaints you heard about ember, though I think they've started to fix that. It's boring work and hard to make good docs, but it's so so important.
