I'm wondering if that crank would work for a leftie?
So I guess the answer is, it's whatever you're used to. Using my right hand for mouse-related tasks was not something I decided on consciously, or due to convenience, since early models (I'm talking C=64 era) did not have the handed designs of today's mice.
Kidding aside, I am a leftie and feel same way. I guess that is where the mousepad was when I learned.
But that is a crank, it requires a bit more dexterity, like holding a pen.

Sounds like Apple did the right thing in that case, but I'm not sure how one could move the crank over to the opposite side. Maybe by turning it upside down and having the controller buttons at the top?
