kinda see your point gav but according to ms before vista came out they were planning on a points system for oem 9 points for board change that kinda thing as alot of people would be using hardware not fully supported by vista and then upgrading so they were plannning to give oem users a little grace the frist 6 months or so of release
so everyones arguments here maybe completely wasted as if they did do this then he is doing nothing wrong
