...or scrolling the content vs. scrolling the window (video for Apple's "natural scrolling")
I'm a happy Lion user now and (as many of us know) by default, the scrolling mechanism is reversed. The first tip on every Lion related articles is about how to change it back to the normal way.
I think that the scroll function is a highly well known pattern, so it's hard to explain to users why the new mechanism is better.
Personally, I didn't switched back because I adjusted to the new system super fast. In my opinion scrolling the content is much more comprehensive than scrolling the window as we used to.
Is there any research to confirm which method is better? Are we able to teach the more straightforward but less known pattern or will everybody change back to the good old regular scroll?
