Every time a new Ember RC is released I read a little more about it, and I have to say that this time I'm actually considering giving it a go.

This probably seems a little weird - why wouldn't I want to give it a go? I guess it's because I've been using AngularJS for several months now and learning something as opinionated and complex as Ember is a pretty hefty investment in terms of time and effort.

seivan mentioned ObjectController and ArrayController, which I think are really cool. Does anybody else know of any other features that might whet my appetite and convince me to jump on the Ember train?
