Huh, interesting. I just tried this, and it's indeed quite comfortable to use the index finger to operate the trackpad and the middle finger on the buttons. Middle + ring feels awkward to me, probably because of the size difference between my fingers. I suppose it never occurred to me to try it this way because I usually use my middle finger on the trackpad.
