You said Rev A. of all electronics. Do you have any data to backup such an assertion ? The fact is, Rev A.s only get more publicity, I have yet to see any data that indicates a higher number of affected to shipped units.
Again, blowing things out of proportion. That other guy that bitched about the Rev A comments was right. I bought a Rev A MacBook unibody in 2008, the only problem I had with it was a bearing noise that didn't impact function. Now I have a 13.3" MBA and don't have these issues for now (and probably won't have them ever).
Wow!!! You ask for statistics on the RevA thing and then you use your OWN AND UNIQUE experience to argue... That's not fanboyism at all, dude!!!!
The Rev A curse is common knowledge (and common sense too). One of the most expensive parts of every product development is quality testing. Good brands do a lot, but nowadays, with the pressure to develop fast and cheap products, quality testing is not as good as it used to be (or/and products are not as simple as they used to be). The thing is that everybody knows that first adopters are late beta testers, not only in electronics, but in cars, etc.
The reason is kind of obvious: the manufacturer makes a series of tests in as wide as possible conditions. Once you put your product in the market and real users, with different knowledge, different situations, different configurations, etc., the number of variables is much higher than you tested for. Then is very possible that things that you did not observe, actually happen in the wild. With time and complaints from users, you polish you original design to a much reliable one. THAT'S A FACT. Are all users going to be affected? Obviously not: the big mistakes are already found in regular tests. These problems affect to a limited number of customers, but still might be significant.
