iPhone Duo wins over user during five-day vacation

The author took two iPhones on a five-day vacation, initially considering a switch back to their other device due to frustrations. They cited broken apps and unfamiliar gestures on the iPhone Duo as primary annoyances. The Google Search app froze on multiple occasions, which was a major source of irritation. Additionally, the author found using Touch ID cumbersome for Apple Pay while holding other items. The iPhone Duo uses Touch ID instead of Face ID, a feature that distinguishes it from the author's other phone.

Despite these issues, the author ended up using the iPhone Duo more than the other phone during the trip. The device proved durable, surviving multiple instances of being sat on and dropped at least three times without breaking. The author noted that they did not unfold the iPhone Duo as much as expected, describing the action as feeling like starting an intentional screen time session. The phone also has two rear cameras compared to the three on the iPhone 17 Pro Max, with a 10x digital zoom versus the other device's 40x.

The author had roughly half a dozen conversations with strangers about the iPhone Duo during the vacation. A future version of the device is said to support Face ID. The iPhone Duo costs $2K.
