A really common response to that is, "well, malware share on Macs should track the market share of Macs; it doesn't, ergo Macs are more secure".
This is, of course, silly. We haven't hit "peak oil" for Windows infections. A new Windows worm still pays off wildly better than a Mac worm; writing Mac malware is economically irrational.
