A point I've been trying to get to, with all three of Android, Linux and Windows, is a point where rather than "logging in" to some cloud syncy thing I have a text file somewhere containing exactly the steps that gets the system just how I like it. And then I just blow away my OS. Repeatedly. And indifferently. Because I can set a new one up in an hour. I've achieved this zen state with Android. I'm close to it with GNOME Linux, but there's a *couple* missing steps in my text file still.
