Angry granny tries to shut down Microsoft launch party

Hey Microsoft is celebrating the release of their Surface tablet, but not everyone`s happy about it.

During the outdoor launch party in Beijing things got out of hand and the woman was dragged off the stage by security, along with her husband (guy in red)
What pissed off this granny? Her grandchildren were being kept awake by the noise, and they had school the next day.

Maybe she`s a Mac user?
