Mac UI concept

With the launch of iTunes 11 this morning, I spent a while exploring the new interface. I really like what Apple did with the window buttons (close, minimize). I'm getting tired of the glossy buttons that Mac has been using forever and I think its time to retire them. Applying the fullscreen icon style to the close and minimize button would really tie the UI together and be one of the final steps towards kicking gloss out of OS X.

Thoughts?
