I have used all 3 major OS (Windows, Mac & Linux) for at least a decade each, and I review my current choice every few months.<p>I have regained a lot of sanity by realizing computing happens within platforms, and regarding the OS as just plumbing. My platforms of choice are the web (for hypertext), elisp text applications (for interactive development, task management, email), and Unix.<p>I only need a browser (Firefox), a text editor (Emacs) and a terminal. I prefer to use a tiling window manager (StumpWM), but it's not a big deal to use the WM provided by my current OS.<p>These 3 platforms (web, elisp and Unix) will be long-lived. Whereas native Windows, Mac and Linux applications tend to have much shorter lifecycles. Furthermore, they don't tend to talk well to each other. They are little silos.<p>Also, since the lifecycles are so short, by the time I work out all inconveniences and learn all tricks, the platform is beyond its prime time. This has already happened to me several times. I was really happy with Gnome 2 circa 2005, but the whole ecosystem collapsed with the transition to Gnome 3. Same thing, to some extent, in OS X Tiger-Snow Leopard. A really nice ecosystem of indie applications that has slowly lost a lot of momentum to iOS.<p>That said, I prefer to use Linux because it's so component-ized I can always replace frustrating things, and nothing gets pushed into me by a corporation. Plus code is open, and some userland things like Nix are so unique. And first-class centralized package management is great.
