I can see people rushing out to buy a pc with Vista but come a year down the line parts of it aren't exactly the most current anymore & maybe the video or sound card are no longer supported by the maker, BANG! Vista no longer works properly because those parts are now disabled until you go out & upgrade them to the latest version. At least with XP you can stick with what you have because it's not going to switch itself off if the video/sound card is getting a bit long in the tooth.

Driver revocation is the biggest mistake they've made with Vista & anyone downgrading to it is going to pay big time for it in the future, wait till they charge for "essential" updates.
