Left me give you another set of "anecdotes":
Companies that are great with problem solving methodologies can find the root cause in hours, days, a few weeks, a couple months. We are talking here about solving a manufacturing quality spill, not finding the cure for Cancer. It takes Apple for certain issues years to first acknowledge the issue, as well as to implement a preventive action.
That they have great policies to replace the broken device with another one is another story, when in reality they do a really poor job executing their problem solving process. And there is no guarantee that the problem will not happen again to the same customer as what they typically give you is a replacement device containing the same design flaw or coming from the same manufacturing process that has their share of variation.
I see that you are in Italy, and there is no way you had received the first shipments of Apple products when there is new product launch, most of them come to the US first, and in Europe probably to other countries to before they get to Italy, so I give you that that you may receive different batches of production therefore you experience a lower probability to get products from the production mess that Apple OEMs go thru when launching new products.
Additionally design problems should be caught during product development and validation testing at the latest, not by the early adopter loyal customers.
Please check back my previous posts, don't even bother reading my comments again, as I am sure you read them pretty well, but as you had demonstrated refuse to acknowledge reality, go to Apple's own support website and do a search about how many 'anecdotal' cases are out there.
Apple is great quality company, I give you that, but to me it means that they provide great return on the investment to the shareholders, there is no doubt about it. You are confusing the quality of the product and the manufacturing process used to engineer, design, develop, launch and improve them with the company image, the perception of customers that came to Apple just a few years ago and their economical performance plus some surveys that reflect on how well the treat their customers when they face a difficulty (which is better than any other consumer electronics company out there).
I'm finding more annoying than the actual Apple product's quality issues the fact that there are plenty of customers that have so low quality standards and refuse to accept the reality, Apple's manufacturing quality is subpar and they have a solid record of being mediocre at actually resolving the root cause of the problems.
Robust products work well always, they withstand regular use and abuse.
Please go to your nearest Apple Store and try to get an appointment at the Genius Bar while you are there, count how many customers are actually waiting vs those that are actually buying.
