We're thinking of retiring our old dinosaur of a computer. I'm not even sure what kind it is, all I know is that it is an IBM clone, and we've had it since 1997. My dad keeps telling me to get a Macintosh mini-me (or is it mini-mac?) he has one, and swears by it. I asked him what kind of virus-protection software you would need for a mac, and he basically said that macs don't get viruses. Any truth to this?
