Well, then you haven't been using macs for a decade, but for a year, times ten (and that's totally fine, unless you're leaving arrogant comments on HN about "why we tolerate this or that"). I've been using macs for about 5 years and I still learn new useful features and shortcuts, and having 3 modifier keys is so useful (e.g. emacs + iterm2 + spectacle) that I can't see myself going back to linux/similar. ETA: also, brew is lovely for people who want a stupid simple package manager
