Also Mac is extremely easy to upgrade, plus, you don't get nagged every five minutes about system updates.
And when it comes to hardcore video/photo/ect. editing, you'll probably have your eye on a certain program and just choose whatever computer can run it best.
Also you can run windows on any newer Mac. Without emulation.
Plus theres Wine/Crossover.
Mac with BootCamp:
Pros: Photo editing (according to maccigarettes), Video editing, sleek interface. Professional, Fast, upgradable, gaming.
Cons: Viruses. (of course you can probably fix them from the Mac side.)
