I am happy that the days of needing a watch are behind me. I think the primary annoyance centered around the fact that I'm left-handed. Since I'm left-handed, I only really have the coordination to strap a watch using my left hand, meaning the watch itself is on the right hand.... this interferes with using a mouse with my right hand! The watch would get caught on the edge of my desk. Maybe the fact that I'm a lefty…
Same here, so not that weird.
I have actual reasons for this, which are (1) using a shared computer (as a kid, and later the computer labs at university), having to rearrange things got annoying after a while; (2) the nicer mice tend to be "ergonomic" in ways that don't work when used left-handed; (3) when I used to play computer games more, all the keyboard shortcuts assumed the keyboard was to the left.
Edit: And now that I think about it, the standard cut/copy/paste/save shortcuts also use the left hand. I guess I just didn't notice since I was already using the mouse right-handed well before I finished becoming a proper employed adult.
