We've lost one of our talking points? Really? I've had this macbook that I'm typing this on for 4.5 years without an ounce of anti-anything on it. I love PCs - couldn't imagine using my MacBook for real work, but it is my only home computer and to say that because of this article it's lost the edge on PCs for being vulnerable is a bit out there. Now, I know it is stupid for me not to have some anti-virii, etc, but I honestly don't keep anything important on this computer, plus it's 4/5 years old, so if it got "sick" it wouldn't break my heart to have to get a new MB Pro But if I bought a PC and used it on the interwebs for an HOUR with no anti-virus, I'd be seeing blue screen of death (or my friends would all be getting spam from me).
