In reality this isn't that much money. When you consider that the entirity of the DoD runs on Exchange. They are heavy users of sharepoint and in addition to all the Desktops the DoD uses Windows on most of their deployed systems you quickly get to a staggering number of desktops and systems. Then we can start on office by then your at maybe half the actual cost. If you look this was sold to a reseller and I would venture a guess that a good chunk is for actual deployments integrating CaC cards and working with Network operators. While I would fully support the DoD taking the plung and switching over to Linux for desktops the truth is I don't think there is a Linux vendor out there (Including Red Hat and Oracle ) that has the support infrastructure to deal with the amount of support the DoD will require. It would make more sense to get the DoD migrated to a standards based deployment that was inter-operable between divisions and vendors. Then you would see Linux support shops start to take away friendly divisions and slowly get market share. Without that your never going to see anything but a Microsoft monopoly.
