What opperating system do you think is the best Mac, PC, or even Linux?

I like Mac personally even though I don't have one *cries* but I'm gonna save up for Macbook and itouch package . I just want to see what you guys like better cuz my family has several different opinions. (sister is a die hard linux fan and dad being under microsofts spell of evilness)

I'm not one of those people who thinks operating systems makes computers but PC wins based on having more customization.

of course pc becuase they have the best windows hehe no puns intended
