Well, personally I like PC.
They both have their pros and cons though.
My main things I disliked about my Mac laptop was the Browser(Safari) and the whole thing where there is no right-click on the mouse. The keys being different and the desktop and everything being different was incredibly original and looked great, I was impressed personally. But there were many useful features like right clicking taken away that tended to confuse me and hold me back on a lot of subjects that I wouldn't even have to think for with a PC.
To be honest, PC and Mac are almost exactly the same except the layout of everything. I've had friends say a Mac was A LOT faster then a PC. Well, I say Bull crap, because my pages load in almost less then a second and loading faster then that isn't going to help anyways.
PC is overall the best, if you ask me.
Mac is good for buisness work though from what I hear.
