If you're a terminal nerd you have to go through a couple extra steps with OS X that you don't with Ubuntu, sure. But if you're the sort of person who gives a flying fig about the kinds of programs homebrew installs for you, are you really going to scream, "WHAT? I have to spend five or six minutes installing Xcode's command line tools and the Homebrew package manager? THIS IS UNACCEPTABLE!" and flip over the table in rage?
