Why All the Macs?

It seems to me that Macs are the computer of choice in the photography industry.  Can someone (preferably a photographer) please tell me why this is?  I’m not looking to debate; I’m just genuinely curious how they have become so prevalent in this industry.  Why do photographers prefer them?

  • Is it because of compatibility with the iPhone?
  • Does the higher price tag of a Mac equal better performance or savings in the long run?
  • Are there more tools/software available for photogs?
  • Are they better for tracking expenses and clients?
  • Does the simplicity of their design correlate to faster work?
  • Is it simply because they have better advertising than PCs?
  • Are they better for storing, organizing, and archiving photos?
  • Do they help you get paid on time??
