I have used windows phone, linux, chrome OS, Blackberry's palm-like UI over the years, but I have gotten the hang of each over a small period of time. Apple devices however, are simply counter intuitive for me.
Apple seems to design UI for 2 types of people.
1. Old Apple users 2. The person whose phone use is the same as it was 15 years years ago + an app launcher
Because of those, I have seen 2 negative trends in their UI/UX design :
1. Sticking to old but familiar (for Apple customers) ways, even if they are cumbersome. (itunes) 2. Front loading everything that is heavily used by a layman (their launcher and quick setting menu), and hiding everything else behind a bevy of menus in settings.
If you have not grown up thinking like an Apple user and want to do anything advanced (my demographic), then their interface is incredibly alienating. The only other time I have felt this way has been when using SnapChat. (although Snap's was a lot more egregious than Apple)
I used an iPad for 2 months this Summer, and swapped it out for a Fire HD 10. As much as the iPad was fast, I can't be happier to be back to familiar territory in Android (even if it is on 5.1 Lollipop)
Granted, that my demographic may be the minority, esp. in the US. But, I can't help but feel, that the incessant praise showered on Apple's devices is partly because of the greater familiarity people have with those devices. And, that Apple won't fare as well if they were to be evaluated by an audience unfamiliar with their brand and devices all together.
