So what does an OS purist like yourself run? BeOS? Plan9? All OS&#x27;s suck. They&#x27;re just horrible. But so is everything else. It&#x27;s all flawed in one way or another. Windows is flawed, OS X is flawed, our tools are flawed, our languages, our editors - everything. If you want perfect, you have to throw away your computer and somehow live inside Knuth&#x27;s books.
