The examples provided to describe the difference between controllers in Ember and Angular do not appear to be different to me at all. In fact I'd argue that they are identical. It feels to me as though the author is wanting them to be different because maybe it's a style preference from the templating perspective?
The examples were to show how $scope is used in Angular vs direct use of the Controller/Model proxy in Ember. This makes a bit more sense to me, personally.
Interesting - didn't know this. $scope is injected by Angular and available to the view - is this the same thing? I didn't think Ember had a DI aspect to it.
