I agree .. I'd also like to know how they are getting usage figures this early.
Not that they mean anything anyway .. all from sales of new PC's on the run up to Xmas, and of course people will experiment with the new interface when they get a new PC ..
a) they have no choice
b) a number will be intrigued to see what's there.
Neither suggest they actually like what they see .. only time will tell that story.
What's interesting is that they feel the need to "hype" the usablilty .. I don't remember them doing this with the release of other Windows versions .. at least not this early.
