An Engadget columnist argues that following the launch of Apple's first foldable phone, the iPhone Duo, the company should now extend the concept to smaller "flip" phones and larger foldable iPads, mirroring the range of form factors already offered by Samsung, Lenovo and ASUS. The piece contends that having solved the engineering challenge of a thin, durable folding hinge, Apple should be able to scale the design down for a compact "iPhone Flip" and up for a foldable iPad Pro, rather than taking years to diversify as it did in responding to Samsung's original Galaxy Z Fold.

The author envisages an iPhone Flip resembling an iPhone 17 that folds horizontally with a small external display, similar to Samsung's Z Flip, noting such devices are typically half the price of larger foldables and have become popular with mainstream users. For tablets, they suggest an 11 to 13-inch foldable iPad, smaller than the 16.3-inch screens used by ASUS and Lenovo, which could function as a tablet or fold into a laptop-style or vertical multitasking mode, with Apple's software experience giving it an edge over Windows-based rivals.
