Only problem is the 10M they "saved" was based on the assumption that if they had chosen Windows, they would have had to keep upgrading/paying for new versions.

Only problem is the 10M they "saved" was based on the assumption that if they had chosen Windows, they would have had to keep upgrading/paying for new versions. This assertion is dubious at best. I would imagine most computers/departments would not have been required to buy each and every new Windows/Office release. A great counter argument to mine (not that any of you need help) would be to point out a specific Linux feature needed in the last decade that was "free" whereas a comparable Windows/Office feature would have forced an upgrade.
