Yutaka, you’ve got your head screwed on right 
“everything just works on a mac”; “never has virus issues”; “never needs defragmenting”…
“Ignorance is Bliss!”
Never mind that man behind the curtain!
Had a neighbour once who drove a Chevy for 10 years, told us her car never required service, had never needed an oil change, and she’d only filled the tank maybe a dozen times. She was apparently quite oblivious to the fact that her son used to take care of all those things, and could never understand why other people seemed to have so much trouble with their cars, they should all buy a Chevy like she had and their lives would be much simpler. This woman would have been a MAC user.
PCs require a degree of understanding that not everyone can get their heads around. Some think they can however and usually end up over their heads but incapable of admitting it. These are the people who should be (and often end up) using a Mac where they will be cuddled and protected and made to feel special and better that all others, and all the dangerous toys and bad words will be kept out of sight…
