Mauser,
Apple loyalty is just slightly below Windows loyalty. Until there is some discontinuous innovation that makes the current Apple ecosystem less necessary (as happened with Windows when mobile and browser applications disrupted desktop and server) Apple will continue to maintain loyalty.
It is difficult to give up the ability to pull out any device while I am on the go, take down critical notes in a flash, and know that those notes will be there across all my devices (even the one’s I upgrade to in the future) and automatically saved and backed up so I don’t even need to worry about my devices blowing up anymore. There is nothing critical on any of my devices that is not either backed up to iCloud or to Dropbox, or that is not shared across devices.
Apple has a lock just about as good as Windows did, with the exception that Apple’s hardware sales are larger money than simply the OS that Microsoft sells.
The limits for Apple is penetration of its products, and population growth. I am shocked that Apple is not supporting the Catholic Church and “every sperm is sacred” campaign of a British movies from the 1970s. Life of Brian I think.
Fortunately for Apple, there is still marketshare to penetrate, there are bigger markets yet to start (like autonomous driving), and Apple can always raise its prices as well, as it does.
For me, if my iPhone 6S were to get destroyed, I would buy a 2016 version of the downgraded iPhone SE. But I appear to be one of those rare folks who is finding less joy in each upgraded product cycle that Apple produces these days. Albeit, iOS 11, that will be nice. Alas though, an iPad cannot replace my laptop and never will be able to. And that is not just famous last words. Too many pieces of software that just won’t run on an iPad. But, sadistically, there are too many pieces of software that will only run on an iPad as well and it a MacBook or a Windows machine. So more power to Apple in regard.
From may iPad Pro, sitting next to my MacBook, while my other two iPads are in the other room, and my iPhone hopefully waits for a return email from a girl I met this afternoon (in vain, yes, yes).
