You quoted the unreliability of anecdotal experience and then went ahead and added your own anecdotal immediately in the next paragraph:
I don't think the software quality dropped
> Those who want to experience a lower "functional high ground" should switch to Ubuntu and discover how much further ahead OS X is.I am sure most would agree with you that OS X at it worst is way ahead of Ubuntu, except that's not really the benchmark the users who are going around in circles are using, it quite evident in almost each one of these anecdotal commentary that an older version of OS X is the Benchmark
I think the real complaint people have is that a lot of these people switched to Apple for superior well tested hardware and software, thus avoiding problems that they would not need to wait six months to be fixed.
The key take away I think is NOT that recently OS X has some bugs, rather that the seemingly increasing in occurrence of bugs that more advanced users are experiencing is perceived as a sign on discarding their Test Everything Well Before Shipping culture that important to these people.
> To the everyday user, there is no drop in software quality.
The core market for Apple until quite recently was not the everyday user but developers, designers and the more tech savvy.

I am unsure if your comment was designed to substantiate your thought that "This discussion is just going around in circles with nobody adding real useful commentary to the discussion", if it was, at that you succeeded.
