I'm prone to RSI, and I started using a logitech trackman in '99 or '00. I've occasionally had periods of using mice or trackpads, and extended use of either causes flareups. I've never had flareups with a thumb ball, even with pointer-intensive use like CAD, FPS and graphics. So I keep returning to them -- I've been using them more or less continually for around 25 years. So for my body, it's a clear win on ergonomics; ymmv.
- boomskats 2y agoI can second this. Same story, been thumbing it for 25 years or so. I've also used it through some fairly painful ligament injury ('gamekeeper's thumb'), and if anything I think it helped with the recovery. I remember someone telling me 20ish years ago that, as opposable thumbers, we have more nerves/muscles dedicated to each thumb than we do for the other 4 fingers combined. Not sure how true that is, but it stuck with me.
