What a confusing title and article. I read the first four paragraphs and I still don't really know what power has been unlocked, or how.

I imagine it's supposed to be an introduction to NSPrefPaneUtils; just showing how much stuff NSPrefPaneUtils really covers. It's basically a list of three random .prefPanes that can possibly exist and be used on a Mac and how they get used. Doesn't quite fit in with the article title though, so I can understand the confusion.
