This. Someone tell me what Mac can do that Windows can't.
Vice versa.
And actually I'm not a "maccigarette" I'm just a rare breed of person that owns both systems because I'm not stupid enough to take sides. I use my Mac for audio creation and editing, video editing, graphical editing, and animation because god knows on Windows all the programs for such are over-priced or just plain crap (or available for OSX).
As for my PC laptop which I'm on now, I usually use that for gaming, school work, Skype, and programming software and websites. That is because my graphics card on my Mac is regrettably poop.
