Germany might become an example for other cities that are looking to shed their dependency on proprietary solutions, such as Windows. After Munich, which has already made the move to Linux, Hamburg could be the next big city in Germany to do the same thing.
Munich started the switch to Linux a few years back and the city needed a long time to completely train the people and change the way the administration worked. It's been a long road and Microsoft constantly pressured and lobbied the people in charge to change their mind. In the end, Munich managed to become a city that uses only open source and it's an example for other city administrations to do the same.
