Is Linux really losing market share to Windows? (Linux-Watch)

I would never run any of my servers on anything but Linux!

However, many educational institutions almost lock their students into using Microsoft on
their desktop/laptop. My wife is working on a degree, she prefers Linux but many online aps
via the online service Blackboard will only work with IE. Many of her "Professors" require
that all submissions be in one of the MS formats.  :(
