Speaking of "natural scrolling" it is horrible because most scrolling is downward and "natural" is an ergonomically inferior pushing action instead of pulling. It's only natural on the actual display itself. Anothe affront to nature by Apple, along with killing the headphone jack.
It makes sense on a trackpad too which is what the majority of sold Macs come with. You’re “pushing” the document, not moving the scroll bars. Seems perfectly natural to me. My fingers move up, the document moves up; just like what would happen to a piece of paper being slid up a table. Yes, it’s less direct than touching the screen, but it makes more sense for the model of UI they’ve been going for over the last 20…
It's totally a matter of personal taste, both are objectively right depending on what one thinks the thing being manipulated is.
