In my opinion, the people who claim Mac is rubbish and that Windows the better haven't had a proper experience on one.
I'm going to take heeby as an example (sorry

)
He hated them, thought Windows beat Mac in every aspect until he went on a friends mac. A real one and not a store one which has been battered.
Suddenly, he's converted!
Also, the fact that people
downgraded to XP and Microsoft offered this to people shows it was a complete disaster of an OS.
I don't see Apple giving out downgrades; do you?

Oh and I haven't got a clue about servers; but i think people use Linux more for that more. Since its less about User Interface =/
