I like the idea of an option between the two interfaces. It is consistent with the idea of Facebook as a platform although I would hate to see Facebook become another MySpace. For my part I dig the new interface and have been using Facebook a lot more since I was switched over. - Paul Jacobson

I also prefer the new Facebook, but that's because they've added a ton of new features. Facebook hasn't done a good enough job promoting these new features and showing how they're linked to the new design. - Marshall
