Good lord... just let people use what they wish.
If they feel windows is "better" for reasons X, Y, and Z, fine.
If they feel Linux is "better" for reasons A, B, and C, fine.
("better" is a wildcard... easier/more powerful/etc/who cares)
Stop trying to make people feel dumb because they prefer apples to oranges. Seems like this argument REALLY stands the test of time -- but never goes anywhere.
