Going back to Apple when you learn from your mistake is pretty expensive. You benefit from Apple resale value when you try to get out of the ecosystem but Android/Windows resale value is terrible.Like others have commented, I don't see the sacrifices either. It's not as expensive to go to the android side as it is the Apple side. On Android you have a pleura of choices of devices. For the ease of use of the apple ecosystem you get a walled garden, inflexible limited customizations, and limited hardware configurations. What has worn on me is the arrogance of apple dictating what is good for the user instead of choices. Several generations of inferior antennas design and baseband chips which in a stubborn wall garden your stuck with what's provided.
I not going to come back to apple as I'm done with the inflated cost and short comings that shouldn't be forgiven like any other manufacturer. in phones apple has stopped even trying to push the envelope on design or functionality. Macs being more and more nonupgradeable by the end user. the ipad being a great tablet has them in the driver seat but.... you see firsthand the impact the surface line is having on the ipad. They are trying hard to shake the media consumption device label. They are now trying to market it as a productivity device which is not what it is. They haven't made the inroads in schools and the corporate world like they thought they would have. But that is another discussion.
IMO they are by purely based on what's happening right now will be taking a hit this year in sales of the iPhone. Their nature of always waiting for someone else to push the envelope and then so called refine the idea doesn't work when teams are collaborating remotely. Alot of things sometime get missed when you can't be side by side getting things done. IMO they will have to push back the launch or otherwise release a phone that will be a minor update like this ipad they just dump out with lidar added and mostly otherwise unchanged.
