I don't believe they've sold 40 million licenses to Win8. Says who? Someone from inside Microsoft? Of course they're going to say "we've sold tons, people love it, come get yours!"
You expect them to say, "Yeah, it's been a flop. Nobody wants our new OS."?
I want to hear it from the stores that are selling the computers, tablets and OS upgrades. I'd be more likely to believe them.
