I think you hit the nail right on the head here, you have such limited experience that in your eyes what you're saying is true.
You can't claim that because you haven't had malware on two Macs in your small company that every Mac is safe from malware, it's far too small of a test group to make that assessment and when I say small I mean it's completely insignificant.
The fact that Mac. equipment is superior in every respect to anything PC...
Apple make the HW as well as the SW which is partly why there is no malware linking to Macs unless you go looking for it.
Apple do not make hardware. Even iPad manufacturing is subcontracted out the Chinese based company, Foxconn. You may remember this company being in the media recently about a string of suicides at their manufacturing plant due to problems meeting deadlines for the iPad, I think you can see the kind of company that Apple will partner with just to get the cheapest price.

As Monkeh pointed out the hardware in a Mac is almost identical to PC parts, there is nothing special about the hardware in a Mac. Other than the fact you're limited to what Apple provide. I could build an identically specced system for substantially less than what Apple charge, so essentially that extra money you spend is going straight into Apple's pocket and is certainly not getting you better hardware.
I don't really understand why you think that Apple manufacturing the hardware would result in less malware anyway. There is malware out there in the wild, I'm not going to repeat this fact again, it's fairly clear that you're not going to accept it even though you have been given countless sources of information proving it. As I said previously you may remain blinkered but spreading invalid information is not helping anyone, especially those who aren't aware of all the details.
