You can use a trackball for over 8 hours with no rsi.
You move less mass and use fewer muscels with a tackball vs. a mouse, its just kinda obvious. Why move your arm when you can just move the tips of your fingers?

Carperltunnel syndrome is basically repetitive motion syndrome.
DO ANYTHING over and over again in the exact same way will cause the problem. Ergonomics help blood flow, but it doesn't cure the root cause of the problem.
The root cause is sitting on your ass in front of a computer/desk for 8+ hours a day, then going home and sitting on your ass watching television for 6+ hours, then going to bed and sleeping on your ass for 8+ hours. Then repeating this for YEARS on end.
You're not moving your joints the way they were meant to be used (ie - full range of motion, not repetitive robot-like tasks)

Wow, if I took that as personally targeted it would be one of the meanest and most incorrect assumptions i've ever had thrown my way..... Then again it is the internet and you do not know me. Your ballpark assumption would probably be correct more than once.
I can only assume that you are mostly correct about carpeltunnel, I am no doctor or medical engineer. I would think ergonomics play a huge roll in whether or not your doing something 'correctly' or in a way that accelerates harm to the body that we do to ourselves consistently as thats kind of the point, and they push that very hard in the workplace anymore.
Me personally, I run, I play sports, I have other hobbies, I have a semi-desk job where I only sit at a computer 1-2 hours a day usually. All of this causes harm in different ways. I'm sure my knees and back hate that I run. I play instruments which also put my hands in odd positions. I most definately do not follow your prescribed day of lazy.
on the other hand, Fur hit the nail on the head with me. I am on the computer at work half the night at least, then I go home and get on the computer. If I leave the chair, it is to go to bed or to sit in a car to go someplace else to sit and do very little.
