I don't think anyone has claimed that the decline in Apple's software quality was unprecedented. Even if it happens every three years, there is nothing wrong with begging for a stable release once in a while. 10.8 will stop being supported soon and then we will be left with the choice between 10.9.5, 10.10.x and a brand new, unstable 10.11.0. High time for a stable release.
You are absolutely right. My point was that the hyperbole around it all in some cases seems, well, hyperbolic. Other than the mdns issue, both Yosemite an iOS 8 have been fine for me. Obviously others aren't as lucky, which really does suck.
