iPad mini previews iPhone Duo's large-screen experience

A tech writer is using an iPad mini as a stand-in to preview the experience of using the upcoming iPhone Duo's large screen, finding the substitution useful despite limitations. The iPad mini's 8.3-inch display is slightly larger than the iPhone Duo's 7.6-inch screen, but smaller bezels on the Duo reduce the difference. The writer mirrored their iPhone app layout and used a Wi-Fi hotspot for connectivity, primarily running apps full-screen or split-screen. The experiment, conducted only when carrying a backpack, confirmed the writer's enthusiasm for the Duo, noting that returning to the iPhone 18 Pro made its screen feel extremely small. The iPad mini runs iPadOS, offering more multitasking flexibility than the Duo's iOS.
