Apple's iPhone Duo: A polished foldable with a hidden crease

Apple launched its first foldable smartphone, the iPhone Duo, on September 9, seven years after Samsung, featuring a refined interface and a nearly invisible crease, though its high price targets a niche market. The Duo folds into a passport-sized device with a 5.4-inch outer screen and opens to a 7.6-inch tablet-like display. Apple optimized app transitions with smooth animations, adaptive layouts, and a split-view mode for multitasking, drawing heavily from iPadOS design. The device uses innovative layered materials and a nanotexture finish to hide the fold, but its stiff hinge and 2,339-euro starting price may limit appeal. Analysts predict 7-10 million sales, potentially boosting a market that holds just 2% of global smartphone sales.
