I can understand wanting to keep the aesthetic of a quill stem though, and not everyone is concerned with the ultimate stiffness of their setup. Believe it or not, some people are entitled to like what they like.

To say quill stems are "obsolete" is a little ridiculous. Yes, newer things have been developed. Are clips and straps "obsolete" since the introduction of clipless pedals? From a transportation standpoint, some could say bicycles are obsolete.
