Seriously? Platform wars? Yawn. Wow, an ad campaign famous for dumb oversimplifications doesn't thoroughly go into all the technical details about Macs and viruses? I are shocked.
The more popular the Mac OS becomes, the more it becomes a target for viruses. If Apple is going by the market or anticipating future problems due to increased popularity, so the hell what?
Smugness over choice of OS is one of those geek culture things that I never have and never will get.
