> How many have stuck with Linux 2 years out? 5 years out?
IT@School (see another comment for details) seems to have stuck with it for at least 6 years, to go by the retrospective on their webpage [1]. And they show no signs of migrating back to Windows yet.
It may have helped that in this case, there was (AFAIK) no widespread officially sanctioned use of Windows for governmental purposes to start with. I don't think MS could get their foot in the door in any meaningful way before the FOSS spirit took over. I do faintly remember MS trying to lure the government with nominally priced e-governance offers, though.
