I agree that Conan isn't innocent in this. He says he won't allow The Tonight Show to be moved back a half hour because it wouldn't be The Tonight Show anymore. Regardless of if he really belives that or not, it's obvious it isn't his only motive.
But having said that, I really don't care who is right or wrong here. All I care about is who makes me laugh. Conan does, Leno doesn't.
