I have a copy of Win Xp Pro which I was given free by Dell and as far as I know, it has never been installed on another computer. I read the terms of the EULA and I don't recall about it saying that it HAD to be installed on a Dell, just that it needed to be activated by MS after 30 days. Now I'm not a very attentive reader and I only skimed through the EULA but I would like to know the opinions of people more knowledeable than me...
