Flipping from M$Office to Google apps is one thing, but flipping from XP to Linux is an entirely different matter regarding TCO. What nobody seems to be discussing here is centralized management and security when it comes to access and control over the desktop. It's one thing to re-train your busy bee workers, but you would need an entirely new IT staff to work with the centralized management tools for a fleet of Linux desktops. If you want a mature set of tools then you are going with Novell or RedHat anyway, which doesn't seem that politically or monetarily different than Microsoft and the cost of your IT workers with expertise on enterprise managed Linux systems is 15-20% higher than getting a cast of MCSE's to keep everything in top shape for you.
