Ending of the movie Inception with Leo DiCaprio?

To me there were several things that sort of imply that he is still not in reality. He has obviously been away from his kids long enough that he has sort of gotten very desperate, to the point that is risks his and the lives of others with no second thought, yet when he gets back his kids are exactly the same age as when he left. And there were a few other things that just didn't seem real, but on the other hand there were some things like the wobble that imply it was reality, but I am leaning a little more towards dream.
