The iPhone 17 Pro on Amazon (paid link) is a refined classic now available for nearly half the iPhone Duo from Apple’s price since production ended. The Duo offers far longer battery life, but its wide body makes it awkward in one hand or pocket. Buying the foldable means paying a massive premium for a new feature set; pick the 17 Pro unless you need the screen that doubles in size. If you want the absolute latest hardware, look at the iPhone 18 Pro (paid link).
