The advertisements of iPhone and its practical application in real life make you feel as if it can be developed with all functions, so the crazy Apple fans often painfully think: what else can my iPhone do? Mac Funamizu, an Apple fan in Japan and a designer, has recently put forward a new concept: Polaroid iPhone, instant shooting and printing! His idea is to install a shell with print function on iPhone. According to the current development trend of portable photo printers, it should not be very difficult to realize technically. It depends on whether there are manufacturers interested in developing it or not.
