I discussed this issue with thorwil on IRC a bit. As he points out, "OS X capitals rip holes into our page".
I've attached a couple PDFs that demonstrate the difference between small-caps and uppercase "OS X".
Since the uppercase versions of acronyms are so jarring, we've decided to stick with the small-caps version -- including "OS X".
