It isn't the cost, obviously, is it? I'm used to Snow Leopard. It runs fine on my old machine. All my current software and peripherals and drivers are happy with it. So why would I want to upgrade and have to learn my way around a new operating system just to get "features" (sic) that are meaningless to me? Some of us don't need/want the latest and greatest that Apple offers (forces). That is why my cameras are all at least one generation old, my smart phone is so old it is almost dumb, I don't drive new cars, I still read books and newspapers printed on real paper, and my glasses don't talk back to me.
