An anonymous reader writes "It's one of the biggest migrations in the history of Linux, and it made Steve Ballmer very angry: Munich, in southwest Germany, has completed its transition of 15,000 PCs from Windows to Linux. It has saved money, fueled the local economy, and improved security. Linux Voice talked to the man behind the migration: 'One of the biggest aims of LiMux was to make the city more independent. Germany’s major center-left political party is the SPD, and its local Munich politicians backed the idea of the city council switching to Linux. They wanted to promote small and medium-sized companies in the area, giving them funding to improve the city’s IT infrastructure, instead of sending the money overseas to a large American corporation. The SPD argued that moving to Linux would foster the local IT market, as the city would pay localcompanies to do the work.'
