Open Source desktops are far cheaper to maintain than proprietary desktop configurations, says Rolf Schuster, a diplomat at the German Embassy in Madrid and the former head of IT at the Foreign Ministry.
The Foreign Ministry is migrating all of its 11.000 desktops to GNU/Linux and other Open source applications. According to Schuster, this has drastically reduced maintenance costs in comparison with other ministries. "The Foreign Ministry is running desktops in many far away and some very difficult locations. Yet we spend only one thousand euro per desktop per year. That is far lower than other ministries, that on average spend more than 3000 euro per desktop per year."
