One of the few things I do bother to configure is my window manager, but only because it happens to be well designed and make it easy to store all configuration in my config git repo. Too much software put host-specific stuff in settings files (like absolute paths) or just are not stable enough in general that it is worth trying to maintain a portable configuration.
