I used to dread watching an obvious newbie buy a game like DOOM II, because I knew that about an hour after they left the store, I would be on the phone with them, holding their hand through the excruciating process of making a boot disk. A large percentage of those people would eventually wind up returning the game anyway. My boss and co-workers had been working exclusively with Macs for so long, that they did not even realize how good they had it. I replied then, and firmly believe to this day, that we could not operate our company the way we do if it were not for Apple and the Macintosh. Macs have a 'long life'.
Macs are easy to 'Set Up'.
Macs are easy to use. Macs require minimal Technical Support personnel.
