If you have made the switch from Windows to Linux, you probably have got that feeling of satisfaction, of things working as expected. Maybe getting everything working was harder, but it felt right. That is the feeling you get when you switch from Linux (or other Unix) to Plan 9. Yes, you lack a web browser, but it is a beautiful system. Then, there are a reduced group of people (like sl) for whom this beautiful system just works. It is the same reason people write programs using lambda calculus or make fundamental physics research instead of engineering. We even get something useful from it from time to time, but that is just a very nice side effect. Or, as Feynman put it: "it's like sex, it may give some practical results, but that is not why we do it".
