normal humans can't edit xorg.conf
Normal humans cannot edit the Windows registry either (I assume its still there?), and you are much more likely to need to edit the Windows registry than you are to edit xorg and similar on Linux.
I recently did the same config change on Mandriva Linux and Windows Vista. On Vista I needed to use a text editor to add a line to the hosts file, on Mandriva I did it though a GUI. I also found it a lot harder to install software on Vista (I am still looking for a GUI app that actually works that will rsync backup a server to a Vista desktop).
