although not as 'easy' as jQuery's `value` this I believe is much `simpler` as it introduces a nice symmetry between fulfillment and rejection handlers. In addition it provides the normally "lost" meta data.

the downside today is  that the following no longer works
```javscript
model: function(){
   return Ember.ajax('/posts')
}
```
Rather a transformation must occure.

```javscript
function getData(event) {
  return event.data;
}

model: function(){
   return Ember.ajax('/posts').then(getData);
}
```

Would it make sense for the "higher level" getJSON to fulfill with only the value, not the entire event? Or should we stick to the event + transform.
