It is the ecosystem attraction, I agree. And Apple knows that and takes advantage of it and can do so because within their ecosystem, they have no competitors. This is, I believe, the reason why they do not have to go out of their way to make their hardware more sustainable, for example install replaceable batteries on their iDevices and AirPods …It’s the Apple ecosystem. I love being inside the blue bubble.
Also, iPhones are the best smartphone out there in the world. It’s simple as that.
