It has found somewhere in the region of 75,000 people who have yet to buy it, or want the opportunity to buy it whenever they please. I suppose this was to be expected bearing in mind that this is the first ever client version of Windows that is based on the very stable NT core, it can't be compared to Windows 98 which was truly annoying for its lack of stability. Anyone who has XP installed probably doesn't need to upgrade, since the OS operates so well.
How dare Microsoft offer a new OS after 7 years!
