the thing you need to realize about macs NOT having viruses is that it's not that theyre IMMUNE, it's there user base is not large enough to warrant such out of control problems. So it's a double edged sword, the more people that buy them the sooner viruses become a daily fact of life for a mac user. In fact a virus for mac does exist to prove it could be done. So right now it's a good selling point for the novice user, but in my 15 years of using PCs i've NEVER had problems with viruses, it's all about begin educated , vigilant, and using common sense, (and i've visited numerous warez sites as a youngin')the average PC user can as well avoid viruses with little effort, but they have to be willing to make that effort, much like avoiding an std, it can be done easily.
