The next time the French parliament opens its doors, they will be serving Linux. According to this “Business Week article”:http://www.businessweek.com/globalbiz/content/mar2007/gb20070312_042781.htm?campaign_id=rss_daily , 1,154 computers will be switching to Ubuntu Linux from Windows XP, including all of the MPs staff and personal PCs. France has had a long history of embracing open-source software like Open Office and Firefox, but this will be the first mass switch of operating systems.
