deano, puto, when u install windows on mac, you can choose to start on it by pressing alt at startup, but if you dont press it, you dont even remeber you got windoes in the machine.. cos if u dont do anything as usual, just press the power button it starts on leopard anyway, so i mean, you dont even remember you got windows in ur machine, and the DVD of leopard comes with all drivers needed for windows, so it is ok, believe in the king.
