I agree. The fools. I work in IT, and have type a lot of things in caps, like certain DNS names, acronyms, and a few other items. At home, I use a Shift-JIS layout for Japanese, and it's one method I switch back and forth between Alpha/Kana/IME input. Right-click has come in handy a few times when my wireless mouse has died and had to go on the charger - then have to re-sync my backup bluetooth mouse.
To extend this discussion - I rarely use my backups. Let's get rid of those!
