As much as you might want that to be true it's just plain twaddle. W8 has so far been recorded as selling at roughly the same velocity as W7, the best selling OS of all time.
With the upgrade price being typically a third that of Windows 7 that would make it a bit of a comparative failure then. At £25 it should be shattering records willy nilly.
In fact since release W8 has already outsold the entire Mac OSX installed base world wide![]()
Well that's a meaningless statistic if ever I saw one.
