100,000,000 so far produced. So scale isn’t an issue. It would simply mean Apple adopt the technology and have a superior advantage over its competition. But Apple is beholden to the shareholders ( of which many are not happy at the moment )
Apple needs to do something to shake up the iPhone line up. Because yearly adoption of new iPhones is down. And people have been vocal about the competition expanding into folding devices. People want something new. And the same old formula isn’t cutting it.
Image is king. When someone can’t tell if you’re holding an iPhone 12 or a 15 , something needs to change.
