I'd expect a loss of productivity from using OpenOffice that far exceeds the cost of Microsoft Office, plus ongoing losses in productivity as staff try to cope with its incompatibilities with complex Office documents that probably arrive on a daily basis. However, staff productivity is not generally a major concern in local government offices, as far as I can tell. Maybe Munich is different, but I doubt it...
