Should there be an $http example in the "With Promise" topic?

On the "With promise" documentation under the "Basic usage" you show only the example getting data via $resource, but it would be nice to show an example using the $http object or any other ajax call.

I believe that in that example it might not be clear to everyone that you have to use the $q object to return a promise, if you're going to use another kind of asynchronous call.
