Spit: Do you mean both are unstable, as the prefix 'Windows ' on the OS name implies, or that both are stable? See, to me, 'stable' means Slackware Linux with the kernel custom compiled for the machine it's running on, with the concept of rebooting limited to hardware changes and kernel upgrades. I've heard the difference between the primary OSes describes as thus: UNIX/Linux you reboot once every six months when you buy mor RAM, Macintosh you reboot once a week when the OS forgets it's supposed to exist, Windows you reboot three times a day because you have no choice.
