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 trackpads emulating a mouse should be considered a poor implementation, a trackpad is different than a mouse and we should utilize that with the design. A trackpad is best imo when combined with gestures, almost as a hybrid between a typical touchscreen and mouse. For example pinching motions, two/three finger tapping, two handed use, etc are all options for a trackpad that don't work (or work poorly) on a mouse.
