I am typing this response with a 13'' MacbookPro, 3.0 Ghz 500 GB of memory and i couldnt be happier. i can play online games. Great video editing and awesome speaker quality for music and video. Speaking of video..... AMAZING screen resolution as well! :D oh and of course.... not a single virus and i download hundreds of questionable files every day :) oh and a little fun fact for you. Microsofts "im a PC" commercials were made and edited on a mac :P even bill gates loves macs ;)
The reason why I exclusively use a Mac, is because I don't have to worry about viruses, Norton, or fiddling around to make this or that work in Windows.
It's not about the hardware.
It's about the operating system. OS X simply gets out of the way and allows you to work or play, without interruptions.
You just get stuff done much, much easier.
It's all based on personal opinion they all have different operating systems and I personally like Mac's operating system much more than anything else.
I say this as a person who have used Windows for many years too, so I have no axe to grind, unlike @__
