I agree entirely with your conclusions.I believe (note: believe) that mice give you an edge over trackballs. That said for most of us, all of us here, for our bodies we are better off using trackballs. I've been gaming on PC since the mid 80s, before mice. None of you are good enough to worry about the difference causing you to fall out of professional gaming. It's more important to take some health precautions. That said, I use mice*.
*Until my precious G3 dies as most gaming mice today are goofy marketing products with either removable parts or 10 useless buttons instead of 4 (+ scroll wheel button).
I am of the belief that mouse has the advantage over trackballs in "certain" games(Ex: fast paced RTS like StarCraft, etc...).
In most other games, it's for the most part about equal.
I DO agree that trackballs are better for our bodies than using a mouse.
However, assuming that a mouse can potentially lead to carpal tunnel because certain medical professionals told you so when the evidence out there is clearly inconclusive in showing any associations between such or throwing an anecdotal evidence that you see people with carpal tunnel switching to trackballs is a completely different story all together.
I'm not even sure how this topic all of a sudden became a "health" issue in the first place.
The place to debate "health" issues is in the "Health and Fitness" subforum, not the "PC Gaming" subforum.
