But no viruses...One of the things that has made me happy I am on the Mac is that I am not subject to the regular waves of viruses afflicting my colleagues on Windows. Think about it -- a Mac virus simply wouldn't work! There just aren't enough Macs out there to enable a virus to spread. It would get out maybe 2, maybe 3 generations from the origination point, and would find that all of the machines it was connected to were PCs... Now I suppose someone could go to the trouble to write a virus that worked on both PCs and Macs... But why bother when 95% of the time your virus will spread based just on running on PCs.
And isn't this an argument for not having a single operating system in the world? Just like with mono-agriculture, we suffer more damage, more quickly, when a pest infests our mono-operating system world.
