I was HARDCORE PC for the longest time.
Then I got my Macbook Pro and finally understood why all the other Mac users sort of laugh at the PC users.... they have a good reason to!
Anyone who has tried both systems will say that the Mac is much easier to use and the better buy.
Mac hands down for Video editing.
PC hands down for gaming.
Everything else in between goes to MAC if you're willing to buy real software and not pirate your stuff.
