@cbae: Yes, and any D&D player would tell you it's two 10-sided dice.

Of course, sales to OEMs doesn't tell you about end-user purchases, or how (if) they are being used or downgraded, but that's a separate issue.
This argument always annoys the crap out of me. It's made every single time, which is why it's pointless. We know how many people use the previous versions, and their numbers were calculated the same way, so it doesn't matter in any way how many are sold to OEMs or end users.
In any case, the numbers may not be as high as some would like, but even though they'll try, the naysayers can't really claim this proves them right. Windows 8 is certainly successful by some measure, and can't in any way be claimed to be a "total failure". That's not to say there isn't still lots of room for improvement and a very steep uphill battle for Microsoft to overcome still. As Paul Thurrott said, this is a very nuanced topic that can (and should be) read in a number of ways, and we won't know the real picture for some time to come (possibly years).
