I'm not sure how many exploits Apple is aware of but hasn't patched yet, but at any given time there's about 200 for Windows. And that's also 200 that they haven't disclosed. If someone really wants to target you, they can get into a fully patched Windows machine with the firewall enabled.

Macs are slightly less susceptible to social engineered attacks. For example, if I get an email stating I have a virus and I need to delete a specific file, I'm going to know it's likely not true. Whereas many Windows users do.
