, i never said the xbox doesnt make money.
xbox became a very successful project for microsoft, but thats just a nice byproduct.
nobody is using linux, because micosoft ran similar projects with great sucess in the past.
e.g. they managed it that big companies got windows (and office) every cheap, same thing with universities and schools.
They conquer a market (like console games ) just to make sure that nobody else can get a foot in the door (or even worse attack them on their homeground)
