I'm left handed but when I have had a physical mouse (or... trackball) it's always on the right. My left hand, at this point, is essentially incompetent at mousing. That's partly because in the computer lab at school the mice were on the right side and often the cables were too short to be moved to the left with easy use. In other shared environments it's good to be able to just sit down at any machine and use the mouse there---the same reason left-handed people often want to still learn right-handed guitar. If I'm on my laptop I use the trackpad mostly with my left, but on the few occasions I've used a separate trackpad device I've put it on the right.
