The article was amazingly entertaining, but I think the Mac vs PC debate is a little overblown.
My background is both that of a gamer and programmer, and I wasted several semesters learning graphic design (the design itself wasn't a waste, but the school... eh, it's a long story). So I have reasonable experience with both platforms.
Each one has its pros and cons. Each one has its strengths and weaknesses.
For my graphic design work (or my husband's film editing) Mac does seem to be a bit more intuitive and easier to use. It seems to be more geared for the artist in general. Apple also provides a great synergy between their various devices, making it easy to keep them in sync.
PCs are great for gaming, programming, and basic home use. A better native office suite and programming IDE (i.e. MS Office and Visual Studio) than anything I've seen on a Mac, if peripherals and other devices can be a little clunky to deal with.
But really, I feel this battle is trying to argue which is better: the hammer or the screwdriver. Each one has it's place, and a good handyman will know his way around with both. Or to put it in a gamer perspective, it's like comparing an RTS to an FPS. Both are good depending on what you want to do.
