I doubt this will work out. They also tried that in many countries, they all go back to using Windows. I hate Windows, but I can envision how much money AND time it's gonna cost them to move out, and I'm sure that they will either run out of money before they do the transition, or machines would have already dominated the earth before they are done with this "transition"l I would believe it much more if they said tha…
Munich did it this way: 100% Linux, no compromises - they didn't even had an central Active Directory so if you required Windows due to software in your part of city government you were on your own - no central updates! They also forced everyone on an ancient OpenOffice 3.x version with KDE 4.x and KMail?

The initial reason for overhauling their infrastructure was certainly due to the proliferation of outdated software, but the consultancy they hired to evaluate the situation made the more conservative recommendation to update everything to the latest version and let each department choose which operating system to use. (Since they were de facto already doing that, just without a reasonable process.)
That this turned into "100 % Windows, no compromises" was probably due to Microsoft politics, i.e. someone convinced the mayor that Linux was the cause of their infrastructure issues rather than bad infrastructure management.
I bet they still have the same problems, except now they also have a few machines running outdated versions of their homegrown LiMux distribution.
