Not who asked, but as someone who bought an iPad I can share at least some which completely threw me for a loop.
How do I search through all the apps on my iPad? I want to see a list, or have a text field where I can type, how do I get one to show up? I try swiping down from the top edge, that gives me a "lock screen". Swipe down from the top right corner, that gives me a _different_ status and widget screen than the one that I get swiping down from the top edge anywhere else. I swipe from the left to the right, I get yet ANOTHER set of widgets I don't care about. Swipe from the right to the left and I start moving through the randomly organized pages of apps.
No, to be able to search for an app, I have to know that if I put my finger in the center of the home screen, right on top of all the app icons which normally I tap to enter said apps, and then swipe down from that position, A FULL PAGE SEARCH BOX MATERIALIZES FROM NOWHERE AND PULLS FOCUS FROM EVERYTHING ELSE?! How the hell am I supposed to "just know this"?
I do like my iPad, but it is full of these kinds of "how am I supposed to know that that works that way?" moments. I got an iPad for my older, less technically focused mother, and I really got the brunt of it then. Text and buttons are indistinguishable in the flat paradigm; you can't increase the size of things like the text that is used to label the apps on the home screen just below their icons (or at least, I couldn't figure it out after much searching); the contrast of UI elements is waaaay too low and many don't respond to accessibility options, meaning things like area dividers are hard to see and thus can't guide the user; dividing up UI elements like the bottom-of-the-screen bar in Apple Podcasts ends up being confusing (is this a part of the "overall app" UI, or is what's on the screen now merely a part of this single view-pane?); apps are always playing "where's the back button" because there is no dedicated "back" button like on Android, so sometimes the back button is in the top left corner, sometimes it's in a different corner because I'm in a sub-view, sometimes it's not there because I need to swipe this menu away, but no matter what, it's never near where my hand always is: the bottom right of the device, so it's always a chore to go "back".
I could go on. What I mean to say is that I strongly agree with author when they say "Apple’s no better than anyone else when it comes to UX"; I'm sure if I got used to it I'd be fine with all of this, just as I and my older mother are "fine-ish" with Android because it's what we're used to. But make no mistake:
