Mark Gurman wrote on Sept. 13 that Apple’s first foldable iPhone, the iPhone Duo, could help make foldable phones mainstream. He expects Apple to expand the line over the next few years with a larger-screen iPhone Duo Max, a lower-spec Duo SE and a vertically folding Duo mini. Gurman said Apple chose the name Duo rather than the widely speculated Ultra partly because three-letter names fit a product family and leave room for Max and SE suffixes; some Apple staff had called the device Ultra. He projects foldables could account for more than half of new phone sales within ten years as costs fall and use cases grow; foldables currently make up about 2% of global smartphone shipments.
