For me i perfer PC. Due to the customization you can do to your desktop. Tremendous amount of games i can play. *cough* Free software *cough* Able to upgrade parts without spending x10 amount of money for almost the same parts as mac. Can have up to 4 to 8TB of hard drive for storage and not having to spend an arm or a leg for external apple storage devices. Able to Overclock and mod for better cooling system.
Pc = A real man machine
not my pic but using it as example =P
Mac = For women or mens that afraid to get their hands dirty
I do admit Mac got some nice and neat product, but when it come to what i do with what. I prefer my PC. Only thing i love about mac is their screen quality =)
