Get a grip man. An OS update fails on one machine and you find it perfectly reasonable to extrapolate this to Apple going to the dogs and that Apple management should resign ? What planet do you live on ? Your blog post is the very definition of overexaggeration.
Those of us who manage larger number of Apple devices have not seen any issues with OS X updates.
Sure there is always the possibility of an edge-case where an OS update can go wrong. But that can happen on ANY OS ... Windows, Linux, BSD.
Sheesh !
