comparing angular to ember-data seems strange, no?
Angular doesn't need a model, it's a MV whatever. Where as ember is MVC. The framework is MVC and it's M is not complete at all. So judging from an overall framework ember is not complete in that respect where as Angular is.
Like come on, 1.0 and hey our M in our MVC framework is incomplete. Um... that's shouldn't even be 1.0. 1.0 to them is the api is going to be stable but not the emberdata, the model. Really?
This is a very unfair comparison between a complete stable release of Angular and an alpha of Ember Data that even tells you it's extremely unstable and not production ready.
