The security issue brings up another point about the 'anti-ms' thing. I am kind of a semi-IT guy where I work, and I end up doing a lot of tech support for friends and family too.
The thing you always hear when someone has a problem is that they have a 'virus'. Honestly, in my experience, it is quite rare to see a seriously infected system. If there is a virus that makes people by $400 computers with 256MB ram and tons of awesome free software installed, then security experts need to tackle that thing asap.
When Mac users have problems the perception generally seems to be that it is just because they don't have the latest macbook or G12 or whatever and their system is old and slow (even when it may not be that old)...it has nothing to do with the 10 chat programs that they have installed.
In cases where someone actually does have a virus, it is usually when someone has been downloading music, porn, or warez and they get a backdoor virus that tells them to 'click here to install anti-virus' which basically opens the floodgates to their system.
