But still, it really not representative of the Apple ecosystem IMHO.
3D Touch on iOS for instance is a state of the art demonstration of how to transparently and smoothly add a layer of functionality to an existing interface.
On the iphone, the "for you" icon is a heart. The "like" icon is also a heart, but the relationship between the two is tenuous. The "plus" button adds a song to my music but I still have to hit "download" to keep that song on my device. I have to double-opt-in to music I want? Make it easy to add music! To really say you like something there's plus, download and like. And then there's still the 1-5 rating, which I just had to click around for 30 seconds to find again. No idea if Apple will feed me more of liked-plussed-downloaded-5-star music than simply liked.
I haven't found 3D touch that useful. I try it all the time but it just feels gimmicky. Half-push to get something, full-push to get the same thing I'd get if I just touched it lightly. Sometimes it's a menu, sometimes it opens up a preview, sometimes a combo preview and menu. I'd bet 70% of people just don't use it because it's too faffy.
And I just remembered Airdrop, where the "air" part seems to be more representative of Airdrop reliability than anything else. Does it want wifi? Proximity? The moon in a given phase? What incantations must I perform to move this photo two feet? Why can it see the ipad but not the other phone, when the other phone can see this phone? Can I add a favourite set of devices so it can find each other a bit more quickly?
Apple are fantastic at simple interactions, when there's one button and three things to do. They can distill better than anyone. But make things slightly tricky and they overload one button with 100 features and start falling over their feet.
You can turn off the iCloud Music Library and sync via cable
Why? What point are you trying to make? It's not obvious and not simple. I also had to google how to do this. Are you claiming that this was obvious and easy?
