I've had 3 friends already buy the Xs Max, All of them said the same thing to me: "If I get an android phone, I lose all my apps". And I tell them everytime, the money you save buying an Android device, you can re-purchase the same Apps and still save a small fortune. It's how I got out of the Apple Ecosystem at least.
I don't really know what you're trying to prove here, Not only does everyone know the iPhone sells well but what are you trying to prove? There are no other High End phones because they don't sell as well? I'm sure there's a car analogy here
Any who, Something I see everyday are iPhones, They are nothing special anymore, Haven't been for a few years now, people buy them because they've bought into the Apple Ecosystem and it is not only painful to leave, it's costly as well.
I applaud Apple for the strategy, Make it hard to leave so people won't. I just hope newer buyers, people who haven't touched Apple products before, Aren't being suckered in, here in the UK at least, I don't know anyone who wasn't already an Apple fan, to go out and purchase the new iPhones.
