You said -- "I can do all that with my PC and play games as well."
Not without inviting 60,000 viruses to join you, too -- unless you fight them off, all day long with a series of programs and security measures and a manual thicker than the doctor's drug book.
I haven't seen a single infection in the Macintosh since around 1991 or so. In fact, it's so rare that most Macintosh users don't even think viruses exist on computers. Boy, are they shocked to find out they're *all* over on the Windows machines...
Are you sure some of those viruses didn't transmutate and accidently infect you? Just wondering....
