Despite being a heavy cell phone user for more than 25 years, it only recently occurred to me that vertical navigation on most phones is inverted when compared to traditional computers. You swipe down to navigate upward, and up to navigate downward. I recently spent time using a MacBook, which apparently defaults to this "natural" scrolling (mobile-style), and I was completely thrown off by it.
I've been using natural scrolling on a couple of my own desktops ever since, mostly as a mental exercise, and I wondered...how many of you folks prefer this method?
I think the big contention comes with touchpads. They are half way between a mouse and a touch screen. Traditionally they acted like mice, you two finger down to scroll down like on a mouse wheel - but you have no wheel so are directly touching the surface. Much more like a touchscreen.
So to me traditional feels natural to me on a actual mouse, but on a trackpad natural feels more natural. I really hate that on the Mac you can only set all mouse life devices one way and not be able to have actual mice behave different to trackpads like I can on Linux systems.
