Pretty good observations. I like the idea of one primary open and one primary closed system coexisting. I typically use both whenever possible. For example, I use OSX since it is polished and everything works well and there is good commercial software support. But I also use linux for tinkering around and for doing things you cannot easily do in OSX (kernel tweaking, general OS customizing, server stuff, different windowing systems like Xmonad, etc).
