Mobile is completely hamstrung, all of the effort went into creating as much vendor lock-in as possible rather than into creating a useful pocket computer. There's all this cool tech on and adjacent to mobile that you can't actually use in any meaningful way because every aspect of it is someone's money patch and they don't want to work together.

At least iOS made the deep and robust AppKit/Cocoa the foundation of its primary kit and then over the years made sensible QoL changes, resulting in something reasonably pleasant to write for. That, and it doesn’t fight you and make you jump through hoops if you’d rather use some flavor of C, C++, or something else LLVM can handle instead of a JVM-something. That goes a long way.

I'm absolutely not a normal user, but I love the experience on the Pinephone, because I can use the same stack as on desktop.
