I don't disagree...such an evolution would be too drastic and unnecessary given the desktop and iPad Pro ecosystem...but to presume that Apple might someday make macOS and iOS intertwined doesn't require a drastic reading between the lines:
- the top feature in the Apple macOS preview is the porting of an exclusive iOS feature (Siri)
- there weren't any huge new features in Yosemite, though the top billed feature is split screen, which was subsequently introduced to iOS9. You can notch that as a victory for the Desktop-worldview...but the other big feature I remember in Yosemite was bringing over Metal, which was introduced in iOS 8.
- for Mavericks, which had many more changes, the two top What's New features are iBooks and Maps...two iOS apps that do not particularly change up the Desktop experience.
- Other developers might disagree with me, but while I've been mostly happy as a developer on OSX, I can't recall the last time Apple added something that hugely changed my experience as a developer...Bash on 10.11.5 is still the same Bash as on 2007...almost a decade ago. The freeing of the Office apps was very nice, though I don't use them so can't say how well they've been maintained. I do know that iTunes and iPhoto continue to be a disruptive shitshow, and nearly every app that I use on a daily basis, from Chrome, to Dropbox, to Google Chrome, to Steam and Atom...are third-party.
For fucks sake, one of the small things that would bring me daily happiness is a built in version of flux. But not only did Apple steal flux's thunder by blocking the iOS flux app and then adding Night Shift, they still haven't added it to OS X, which is where flux originated...and I don't see it as part of macOS.
- And then there's the hardware. I don't pay enough attention to PCs to know whether Appple is still outpacing them, but the rate and quality of new first-party peripheral does not feel like Apple is pushing hard on this front. I love the trackpads (a feature that has followed innovation on iOS), but I want a mouse, and the Apple first-party mice are terrible. I do love my several-years old aluminum keyboard...but the new one didn't seem to be a worthwhile improvement for the price jump.
- and of course, there's the Apple Display situation. No other Apple product would more greatly improve my computing experience and I am more than happy to pay the premium...the amount of time and money I've wasted in researching and buying third-party monitors that for whatever reason, aren't as seamless as the 5 year old Thunderbolt display, had more than exceeded the Apple premium sticker price.
- the iOS App Store has its problems...but the Mac App Store does not feel like an ecosystem that Apple has put nearly as much effort in helping out developers (or consumers)
- the iPad Pro is marketed as "your next computer"
Oops, meant that to be a simple list and not a rant. But typing it out on my iPad was slow enough that I kept thinking of other signs of non-desktop-enthusiasm for Apple :)...you can argue that Apple isn't overtly hampering the desktop...but it's hard to argue that Apple sees as much potential from desktop, based on its recent product releases.
