Seems like the place to post my RSI-related story. I've been using the Logitech MX Anywhere [0] for a while. RSI was fine, I didn't really think about it. Just a handy little mouse, no big deal. Then it broke, the left-click just wore out. So I thought I'd "upgrade" to the MX Master [1]. Mistake! I realised that the smaller – and therefore significantly lighter – mouse was allowing me to use the tips of my fingers to push it round the table, rather than using my entire arm – hinged at the shoulder – to do the same. It's like I'm making it dance around by tapping it in tiny little movements rather than pushing it with one big movement to where it needs to be. It's hard to explain. Either way, that made an enormous difference. With the MX Master, there was much more arm movement. I was in agony within half a day. When I figured out what it was, I switched it back out for the MX Anywhere. Now I'm happy again. It seems counter-intuitive, but for me it works. I don't have very large hands, so that may be a factor.
