But I think you do need some level of consistency to retain customers. Churning models, especially given Apple's otherwise-excellent retention metrics and mechanisms, seems like a self-goal by almost encouraging those buyers to switch after 3 years.

If you bought an iPhone Mini or an Air, but that model is gone at T+3 years, that's a lot more likely to result in you looking to Android, than if you bought an iPhone 13 and want to upgrade to an iPhone 16/17.
