I never thought about RSI, but also I've started having pain/weakness in my right hand last month (that, thankfully, has mostly gone away). The doc said it was tendenitis. I feel like excessive swipe-typing with my thumb may have contributed more than typing to that; but I also play keyboards and it was scary for a second to have that affected. I got myself a vertical mouse; will consider using another layout (which one do you use?). I do type at 75-80WPM (including time to fixe typos), can that really cause RSI? I don't know if I'll be able to pull off even 20wpm with another layout, but looks like it's the next step. Thanks for suggesting it!
