What an inane post.
As it happens I own two BMWs and many Apple products. BMWs are, at best, middling in reliability, and one of mine (a 2006 330i) has been the least reliable car I've ever owned. It is great, even special to drive (they really do have great engineering acumen - it's just that they seem to apply it to the driving experience rather than to optimizing reliability), so I tolerate its bugs, but my next daily driver will probably not be a BMW. My M3 is a weekend fun toy, so sees little mileage, but has been quite reliable.
My MBP is far and away the best and most reliable laptop I've ever owned, including an NEC, a Dell, a Samsung and a ThinkPad. I have never had another laptop last much past two years before it started to break down. My MBP is nearly five years old and remains a pleasure to use.
See? People can acknowledge reality when it comes to their major purchases! Even naive BMW/Apple fans!
The idea that Apple users are uniquely predisposed to irrationally defend their expensive purchases makes no sense to me. Why would they be any more inclined toward that than, say, Asus, Lenovo, or Vaio owners?
