My friend's wife uses CapsLock instead of Shift for each and all capitalization needs, even the sort of capitalization done in this sentence.

See, at least that's not as bad, since you're basically going Capslock -> letter -> capslock, so it's easy to get your brain used to that. With insert mode, you need to think as fast as you type about how many letters you're overwriting.
