how can anyone doubt Ballmer's passion after his sweaty stage march. He ain't in charge anymore anyway. Gates was more methodical evil than passionate and his big moves were all just stabbing someone else to take their place.
I think he managed to buck the trend because, despite not being one, he liked developers (some would say a little too much)
Don't forget Gavin Belson and Action Jack Barker
Action Jack would still be at it but these days he prefers a nice piece of fish.
