In the big multi national corporations that I am involved with, there has been a dramatic shift away from desktops running Windows, to thin clients running Linux that connect to Windows virtual machines. The servers these virtual machines run on are also Linux. The Windows virtual machines exist so that users can run Microsoft's office products and Outlook, and legacy applications made for Windows. The legacy applications are generally being replaced with on-line/cloud based applications, or multi platform applications. In this respect, Linux has been neutralised in the way that Microsoft can still extract tax for the desktop environment for a while, but only a while.
