Not to start a huge argument or anything I just find it amusing that almost everyone who chooses PC does so because they believe they have a vast knowledge of computers. This is not everyone just a good majority.
I honestly don't see the point in getting a PC over a Mac for most people other than cost. I've owned both (many different computers of each) and I can honestly say I'm never getting another PC. Macs are much easier to use, they're much more user friendly, they maintain their speed for longer (all of the PC's I've owned got very slow if I didn't load them with tons of anti virus software), they're better for video editing (final cut etc).
Some may need a PC for other reasons but for my usage Mac is perfect.
