I don't know how they managed to pull this off. They managed to have Windows 8 launch and Surface Pro launch both at the time for hurricane and blizzard. Not even a few days late. I would say their weather forecast is insanely accurate when they have been setting these dates several months prior. Or somehow we are always going to get some intense weather when MS launches something because MS is this powerful?
In some cultures, bad weather coinciding with an important event, indicates good luck and fortune.
