I don't like at all. My experience for iPhones is iPhone 6+ (which was amazing), then I've been at Android world (Sxx series), and now I have iPhone 17 Pro Max, and truly wonder what is the value proposition here. Feels really buggy, UI tries to be Jolla-like gesture-based, but fails to do that, default style reminds that it is made by/for a kindergardener. And there is no "home" button anymore, that resets my virtual position to something safe/familiar, now I'm trying to swipe up/down/left/right, and there is always some new screen layout.
On the macOS side, it gets more locked and buggy and inconsistent with every release.
This is just a general comment for Apple OSs today, not specifically version 26.2.
