With my Mac Pro late 2013 slowly dying, for the first time, I'm considering other venues than Apple.
As for the software fragmentation, I wonder when people are fed up, that they can only use certain features with certain combinations. There will only be a few people who will always have the latest and best: i.e. the latest iPhone, the latest Apple Watch and the latest Apple TV. e.g. I cannot use 2-way-authentication because my Apple TV 3 doesn't support it.
macOS: oh make it stable again.
iOS: oh make it efficient again, this version is unaesthetic, it's beyond words (let's just look at the music app: GUI-catastrophy: rating, swiping, gliding, swipping, swopping... and the audio book player looks differently altogether.) Just because you can do it, doesn't make it good. This music app is crap. Overloaded, overplayed and unusable.
watchOS: Oh dear God, give me an interface which makes sense! I cannot deal with this mashup of icons. The dock was the best idea and the speed increase more than welcome, but the main interface is still a mess.
and there are so many other areas where they need to do things: iTunes store? A tagged mess: the sort order of series is a catastrophy, at least in non-US countries. Indications for languages: another mess.
Sigh. FOCUS, Apple. Simplicity. GUI. Speed.
This is not fashion. These are instruments we use everyday!
