i got stuck with 'vi' at a place a few years back because "that's good enough - they're pretty much the same". I don't mean as main development tool, but on server builds, 'vi' was 'good enough' and also "it's smaller - we need to keep this small". So any time anyone had to do anything on those remote servers... years of muscle memory gone because... oh yeah, it's 'vi' not 'vim'. it was jarring to be reminded of how different they are.
