Exclusive: Apple CEO John Ternus on iPhone Duo, fixing foldable screens, and the end of the no-stylus 'rule'

Apple CEO John Ternus and senior vice president of worldwide marketing Greg 'Joz' Joswiak have unveiled details about the iPhone Duo, their first foldable phone. While Samsung, Google, Huawei and other companies have been manufacturing foldables for years, Apple has been hesitant to enter the market. The iPhone Duo stands out with its passport-style design, Apple Pencil support, IP68 durability, and an optimized software experience for the foldable form factor.

One standout feature of the iPhone Duo is its nearly invisible crease, made possible by Apple's nano-texture display technology. This technology has been seen on other Apple devices like the Mac Studio Display, iPad Pro, and MacBook Pro, and it reduces glare, reflections, and the visibility of the crease. Ternus was impressed by the feel of the nano-texture display, describing it as "beautifully flat" and "incredibly durable".

Apple has also worked closely with developers to optimize apps like Netflix, Slack, and Zoom for the iPhone Duo's dual 7.6-inch screen. The software experience includes a redesigned control system that moves the main controls to the right edge of the screen, making them easily accessible regardless of the screen orientation.

Though the iPhone Duo is the most expensive iPhone ever, priced at $1,999, Apple believes it offers excellent value due to its complex and well-engineered design. Ternus emphasized that Apple aims to build "cool things that people love" while maintaining a high level of quality and durability.
