Mac's great if you want to tell eveyone you have a Mac.
PC is for people who want a computer they can use, have control over, customise, optimise and functionalise without spending money on aesthetically pleasing plastic casings and painful proprietary connectors.... and then again a year later and then again two years later.
PC is flexible computing
Mac is Kit computing
Depends what you want and what you're doing and how much you care about spending more money unnecissarily.
My two cents... (which i saved by bying a PC)
