You will be part of the mac community and be able to speak Appleze. You will be able to share in the joy of owning a status symbol, and looking down on everyone else who has a PC. You will be able to show you are intellectually superiority by your choice in Mac. You will be able to reaffirm your buying decision spending a lot more for a mac that does the same thing as a PC. You will have a support group to to reassure that your purchase of a mac that costs twice the price was better than having that new lens you wanted.
You will be able to tell you friends you have Thunderbolt and Firewire 800 even though you don't have a single peripheral to plug into those ports. You will be able to extol the virtues of a display that is superior, even though most of your friends will not be able to tell the difference.
LOL, just kidding. Macs are just better because they cost more and you would be stupid not to buy one. Everyone else who does photography has a Mac.
