I haven't had the slightest trouble with carpal tunnel or RSI since I switched to laptops. Before then, it was always hovering around.
I can see a couple possible explanations for this (hardly exhaustive, obviously)
1) greater variety in how I am oriented with the device
2) very low action on the keys. I could tap them very lightly, and it'd take.
3) changes in my life circumstances - I'd just gotten married and started grad school, so maybe that relaxed me more. On the other hand, if that were it you'd think having a child would reverse the effect.
I'm not terribly keen on spending 40 minutes standing and meditating every day.
By contrast, I've found that laptops make my RSI much worse. In particular, laptops usually run pretty warm and typing on a warm or hot keyboard gets painful very quickly. My results are controlled in that using an external Thinkpad keyboard is far more comfortable than using the identical built-in keyboard on my Thinkpad.
Discussion of buckling-spring keyboards, which give accurate tactile feedback. You can get them for about $70, and a lot of people swear by them.
Here's my RSI story: Some years ago, I was getting a lot of pain in my right elbow, presumably as + result of excessive Blockout (3D tetris), counted crosstitch, and being polite for no good reason to someone I was very angry at when I was under stress. Rest was not helping. I remember needing to sign a bunch of checks, and using my right hand for the signatures and my left for the account numbers, and it was still hard on my elbow.
The Way of Energy is an excellent introduction to Taoist standing meditation. I worked up to being able to do twenty minutes of just plain standing and twenty minutes of holding a balloon (arms circled at a little below shoulder level) a day. After mere weeks, my elbow problem went away and never came back. Subjectively, I hit a point in meditation where it became obvious to me that I was using more effort to stand than I needed to, and I could just let go of the excess tension.
