Personally, in my last years of using OS X, all I had open was the PDF reader app, a browser and a terminal. I don't know if that was my personal interpretation of the Cloud age, but suddenly I was completely OS agnostic. Incidentally, this led me away from buying Macs, as the operating system didn't do anything for me anymore. I don't know about the desktop experience. Either it seems to be "power user web crawling", for which the cloud is the best fit, or it's about spending the whole day in a random Pro App with its very own user experience.
I'm looking forward for their cars and watches, but I don't care much about their desktop computers. It seems they don't, either.
There are plenty of smart people who see VR finally coming around to be the disruptive technology that it was thought to be 25 years ago.
Still a tough sell to go outside apple simply due to the hardware quality & resale value, but at least we have some contenders today where a few years back there were none.
Also, another really annoying bug is when screensaver goes on and locks the screen. Sometimes, if I try and wake it up to fast it will freeze with a black screen for 60-120 seconds before I can unlock it again.
That is just the smallest of thing, but is so easy to spot and fix and really his square against the level of detail the hardware side gets.
What's not clear is: (i) how much it matters - the core desktop experience is very solid, and between web browsers and MS Office it's not clear how much the iLife(?) apps actually get run.
And (ii) whether it's a symptom of some deeper malaise - Apple still seems to be killing it in other areas so perhaps it's just a weak or resource-starved group within the company.
