Some feel it has to do with the user base being more computer savy/programmers that would be able to make counter measures at will
Computer savvy Mac users? I could see that being a reason not to write a Linux virus... but Mac users? Nothing against the Mac-types here, but... Mac users are so far removed from anything tech-related to do with their OS or hardware that I find that an odd, odd hypothesis.
I would say much more likely that with a bigger install base of Windows machines, that makes them a more likely target. Like if you had to create hardware to allow you to steal cars, would you build it to steal the more plentiful gas engine or the less plentiful diesel?
