Since I started on the Apple experience in early 1990, the QC seems to be less vigorous with some equipment never getting their issues working properly over the years.In my opinion, there is no excuse to carry the same software problems over many successive versions of full releases, not just point releases.
If Apple stopped buying back their stock, they would have adequate cash flow to hire those whose abilities are sorely needed in both hardware and especially software.
I think the motto of yesteryear that "It just Works" is becoming "We Hope it Works" with the advertised features from day one, not a year later. The early adopters are getting an unbaked cake and some years never ever get the frosting as the cake never finished baking.
