I'd suggest you read the definition of "ad hominem attack".
I guess it really is true that Mac users are insecure. (That's an ad hominem attack)
See for yourself: scan a few of these PC/Mac threads, and you will find that, typically,
There are occasional exceptions on both sides, but, if you are honest, you will find that is the truth.
Now, Which side displays insecurity by engaging in ad hominem attacks...?

Full disclosure: I do cartography for archaeology (including mapping long-unused pioneer roads). Since Canvas/GIS was bought by a Windows developer company (and, then abandoned) the only good GIS system I've found turns out to be ESRI's ArcGIS series -- which runs only on windows. So I run ArcGIS on VMWare, and then put the complex multilayer map/photo composites together in (the Mac version of) CanvasX.
I also have a Dell with ArcGIS and the Windows version of CanvasXI. My choice is to use the Mac, rather than the PC -- because the Mac allows me to concentrate on work, rather than on futzing with the foibles of the OS. It's my choice -- based on productivity and reduced frustration.
What is ad hominem about that?
I know the definition of ad hominem quite well, thank you. Your implication that Mac users do not earn paychecks IS a generalized ad hominem attack.
