The pictured devices represent the higher-end OLED screen models, not the cheaper rumored notch LCD iPhone.
Besides viewing and storing pictures, the device can be used to display them on a television set (a wireless remote control is included) or to upload them through a U.S.B. port to a Mac or a Windows PC.
