I have seen this behavior out of more than a few people as well!
Case in point, one guy nearly had a schedule of buying new laptops and desktops about every 18 months as "something would happen" to them that would be beyond his ability to troubleshoot and fix. Because he's 1000 miles away, I've never been able to tell if it has been a hardware, software or wetware issue.
Literally he'd be buying a new PC of some flavor every 3-4 months as the family of 4 would be running into some sort of issue with a laptop or desktop that often.
Sure, those PCs would "only" be $600-1100 but if you look at the limited lifespan for those PCs, it was out of control.
So, 2 years ago I bought him a Mac mini. It really wasn't accepted all that well, as the family was so used to PC thinking, and the Mac represented something else to have to learn.
But my bud figured it out a couple of weeks ago, as he said "that Mac is running as well as the day you got it for me. The PCs always deteriorated and 'broke' and I had to get another one. $600 there, $800 there, it adds up."
He just bought his daughter a 15" retina MBP.
