The German city of Munich is migrating from Windows NT to Linux as the client operation system and to an OpenOffice as the office suite.
The City claims that the transition to Linux guarantees greater independence of suppliers and greater "flexibility in the design of the future IT landscape of the city administration". Additionally considerably lower costs are enabled.
A study by the City considered that Linux desktops were superior to Windows XP.
