"Oh and just to get a different argument going, I played with a Mac yesterday and whats with that little scroll nipple on the mouse? It's rubbish, the wheel is far superior"

Lordy, I must be soooo bored here.......

A wheel can't scroll sideways. I guess you never realised that the little nipple rolls to the side as well as up and down - i.e. a miniature trackball. You can't do that with a wheel. It takes a little getting used to, but once you do, you get really frustrated when forced to go back to a scroll wheel.
