The point that is being made here is the one that this thread and another thread begun by "R3DH3R0" (What to do with my next defective iMac problem?) are outliers to the point of straining credulity, to a stress point that (justifiably) breaks believability for many.
I would agree that most Mac purchases likely go well, and that thus complaint threads are reasonably labeled "outliers". And certainly every reader is within their rights to judge the credibility of any particular thread for themselves.
However, it seems extremely unlikely that every such thread, which have existed on all the Mac forums for the last twenty years, is not credible. Such a proposal would itself strain credibility way past the breaking point.
Thus, we have credible evidence that some of our fellow Mac users are suffering and being treated unfairly by Apple. Thus, there is room for improvement in the customer experience.
I've put a clear and simple specific proposal on the table for improving the customer experience, a no questions asked replacement policy for some defined length of time.
Please observe how none of you have been able to show how such a policy would hurt Apple stockholders or customers, beyond the occasional burping of words like "ridiculous".
Please observe how even though posters can't show why such a policy would not be helpful, posters refuse to embrace such an idea, or even give it serious consideration.
This is credible evidence of a cultural problem in the Apple community, an embrace of a complacent rationalization of mediocrity and the Apple company line. This cultural problem is the ultimate cause of the OP's problem, and all those like it.
This cultural problem will also likely be a significant factor in some other company elbowing Apple out of it's position, because it's a very common phenomena for successful companies to get fat, happy, complacent and sloppy, which creates an opening for the competition. Steve Jobs warned of such a threat continually and with great passion, but apparently my fellow posters have not heard of Steve Jobs yet.
If my fellow posters would apply their articulate intelligence to solving these problems at their source, they would eventually succeed, and thus they themselves would be liberated from having to play the lemon lottery.
But when Apple executives read threads like this, and see that you are eager to line up with Apple against those that Apple has cheated, they see no reason to end the lemon lottery.
Posters in this thread are arguing against their own interests. It may be fun to play the debate game, but if you keep buying Macs sooner or later it will be you starting one of these threads, and then it will be you whom your fellow Mac users turn on.
