>Even failure within the warranty period is acceptable in the consumer market because integrators have it down to a science exhausting people on the customer support side. Long phone queue times, incompetent support agents who have to transfer you to different agents and likely drop the call entirely, silly policies like requiring a reformat/OS reinstall for everything, and so on.

This is one reason why I believe Apple computers last much longer than Windows computers. With Apple, they only sell a few models in high volume. So if there's an issue, everyone will know about it and Apple will often have to do a mass recall or provide free repairs. And since Apple prices are higher, you'd assume that they use better-grade parts on average.
