Without going much in depth, I think it’s about use cases. The iPad is big enough for art, “traditional” productivity, etc. I don’t think the Pro Max screens are big enough for that. Also, it just feels less natural, as with paper. Other than singular cases (there are always potential cases), I don’t think anyone has painted on a phone screen.
Sure, some people like the idea, i.e. to brainstorm concepts. But in practice, I think it’s not so useful (once again, because of screen size) and I’d guess it’s not used very often. And then you have the cost. Not only in terms of money, but in terms of phone design. You would need to add the magnets and charging coils (and btw, move the buttons, since there’s not a large enough flat surface for the pencil), add a cutout, adapt the screen… a lot of space, and a lot of complexity. And this is going to affect every iPhone user, not only those who will use the pencil
I could continue, but in summary, I think value proposition is weak, and cost is very high. I’m not saying a good solution Apple could accept can’t be achieved, and it seems like the concept makes sense to phone makers who create more diversified products (Samsung, obviously). I just think, as aforementioned, that it doesn’t make sense in the eyes of Apple. However, when it comes to the iPad, value proposition increases a lot, and cost decreases, so it’s a much better deal.
