I hate it. Thing with the iPad/iPod/iPhone you ARE touching the screen, so that feels natural. I'm not touching the screen on my iMac, I'm touching the magic mouse so it feels weird.
I'd love to disable it but can't find a way to do it. I have a Microsoft wireless keyboard & mouse combo with the IntelliPoint software installed. I don't get an option for "natural" under the Mouse settings and no trackpad is installed.
The IntelliPoint software only has an option to disable vertical scrolling altogether but no controls over directions. Understandable since Microsoft likely hasn't updated their software. Still doesn't explain why Lion won't give me the option still under its Mouse setting.
So I'm using it but not willingly.
got used to it after one day, no problem at all. people need to be more "open" for new things and stop bitching all the time
