Apple's decision to enter the folding-screen phone market indicates they have resolved long-standing design challenges that other manufacturers have failed to address.

When Apple announced there was going to be a folding-screen iPhone, I figured there were two possible explanations. The first was that they had figured out how to solve an industrial design problem with folding-screen phones that nobody else had been able to solve. The other was that the days when Apple would let a market niche slide because they couldn't come up with a product to fill it that met their standards were over. So, yeah https://www.404media.co/iphone-duo-crackgate-crease-folding-phone/

I was skeptical that Apple would do a folding phone, because nobody has gotten it right and if they could not, nobody could. oops. https://www.404media.co/iphone-duo-crackgate-crease-folding-phone/
