I've been faithfully using Mac for years now and I have a friend who's interested in exploring the possibility of converting from a PC to a mac. I'm trying to compile some pretty good arguments why Mac/Leopard is a better route to go than PC/Vista. Currently he's an average, everyday user who doesn't do any fancy editing, but considering it. Since Vista seems to have reduced its crash problems its predecessor had, can some experienced Mac users give me some ammo to rescue him from the dark side of the force? Thanks a bunch.
