I think this is a major one. The city of Munich is deciding for a Linux solution even on the desktop.

All praise to them.
Munich breaks with Windows for Linux. The German city has decided to switch a significant proportion of its computers from Windows to the open-source OS, despite an aggressive counterpitch from Microsoft. [CNET News.com]
Of course it is only a coincidence that at the same day Microsoft is lowering it's prices.
