Honestly, in the beginning i struggled between Apple's "natural" and the unnatural way of sculling. I was so used to the now "unnatural" version, that it became really weird to think about scrolling inversely. It makes sense when you're touching the screen, but other than that, it didn't make much sense to me. I tried going back to the "unnatural" way, and nothing made sense when i was trying to navigate through the OS.
But it's grown into me, the Desktop switching and just everything makes sense. So yes, i'm using the "natural" version now.
