And it isn't pretty enough 
Then I guess it's better than the one which looked like a dog-eared blank sheet of paper which you might have seen over the past few months. But for a company which spends millions if not billions on logos every year this looks quite amateurish. I mean, anybody can crop the M from the Microsoft logo and give it round edges. The favicon does not carry the most recognizable and popular "Pacman Logo" charactersitics from the Microsoft where the slash between the o and s isn't visible. Without that, it fails to grab the instant recognition one might expect.
