The iPhone lineup
iPhone is Apple’s line of smartphones running iOS. When iPhone Duo was announced in September 2026, the official product page listed: iPhone Duo (Apple’s first foldable iPhone), iPhone 18 Pro and iPhone 18 Pro Max, iPhone Air, iPhone 17, iPhone 17e, and iPhone 16.
According to the press release, iPhone Duo was unveiled on September 9, 2026, with pre-orders starting October 16 and availability beginning October 23 in more than 70 countries and regions, followed by 28 more on October 30. iPhone 18 Pro / Pro Max were announced the same day, with pre-orders from September 12 and availability from September 18. iPhone Air, iPhone 17, and the other models were also part of that lineup.
Form factors and boundaries
The family spans two form factors. iPhone Duo is a dual-display foldable: a 7.6-inch inner display and a 5.4-inch outer display, officially described as 50% larger than iPhone 18 Pro Max when opened, with Split View on iPhone for the first time, a grade 5 titanium frame and hinge, Touch ID in the side button, and eSIM only. iPhone 18 Pro / Pro Max, Air, and the 17 series are conventional slabs. The practical differences for a buyer are screen form factor, size, cameras, and price; compare the specifics on Apple’s compare page.
On the system side, iOS 27 shipped as a free update on September 14, 2026, together with Apple Intelligence and the Siri AI beta (English at launch; French, Japanese, Korean, Portuguese, and Spanish follow in October; not available in the EU initially). Feature availability depends on the model, region, and settings; day-to-day friction such as third-party app permissions or input methods comes from specific apps rather than being a uniform iPhone limitation.
Discussion in the show
Weekly #002 was recorded right after the announcement, before iPhone Duo went on sale, so the participants discussed the event and its online reception rather than long-term use. In the chapter “iPhone Duo 发布：折叠屏与交互的新问题” (iPhone Duo launch: new questions of folding screens and interaction), Xiangyang Qiaomu mentions the “reinventing the foldable” reaction and the viral fold-animation videos, while Guizang praises Duo’s interaction and adaptation design, arguing that grouping system controls on the right and leaning on official components lowers developers’ adaptation cost. In “界面标准与长期一致性为什么重要” (why interface standards and long-term consistency matter), Juzi argues Duo defines three things at once: the foldable hardware standard, the interaction model, and the adaptation target for developers, expecting Android makers to follow. See the launch chapter and the interface-standards chapter of the Chinese transcript.
Yang Pan’s remarks are mostly opinions and retellings: he was waiting for a second iPhone Air but expects a sequel is unlikely after Duo’s launch, and relays the claim that Air’s thinness was early exploration for Duo; he also argues that ever-larger screens and longer daily use make folding an inevitable direction. These are predictions or hearsay, not official information. In “手表、录音与个人上下文” (watch, recording, and personal context), Yang Pan points out the event also included a watch AI feature, and Juzi describes on-device transcription plus a 15-second replay-to-text interaction; see Apple Watch.
On everyday use, in the chapter “语音输入：准确率之外的使用摩擦” (voice input: friction beyond accuracy), Yang Pan describes the friction of switching permissions for voice input on iPhone, and Guizang says battery life and his voice-input habit are why he does not use an iPhone as his primary phone. These are individual experiences and vary by user and system version. All of the above are participant views from the Chinese transcript, not Apple’s position and not independent reviews.
