Again, my main point is that coding Apple apps just takes too much time and ceremony compared to what you get out of it (an app that only runs in Apple's ecosystem). The only way to justify writing an app specifically for Apple products is when you depend on their special hardware and ecosystem features. Or of course if you don't care if your app runs anywhere else. Or if you have resources to blow.
Apple treats software as an extension of their hardware: Generality and abstraction do not count for much, as long as this makes it possible to fit the software tightly to their current hardware. That's nice for Apple, but not so much for a developer who doesn't care for much more than generic hardware features.
