It really bugs me when some ignorant person pronounces judgment on something which he does not understand. HP’s analysis of Munich’s cost of migration to GNU/Linux is like that…
“The city’s IT department points out several errors in the published summary. The migration to free software did not require a thousand IT workers, that is the total of IT staffers working for the city. The firm also fudged the IT support costs, assuming incorrectly that the German city started out with 12,000 open source desktops. "The number of open source PCs rose gradually over the years, to its current number of over 13,000."
Contrary to the firms claims, the use of open source reduces the costs for computer hardware, writes the IT department. The firm also failed to distinguish the difference between a software migration and normal software maintenance, Munich writes. "They evaluate regular updates of the operating system as migrations."

Get over it, M$ and “Partners”, you can’t beat the price of FREE. Even your lock-in needs to be undone only once. That’s always less costly than buying Wintel repeatedly forever. That’s barely competing on price over just a few years. Cheat and lie all you want, M$. Your cash-cow is drying up.
