In May in the tram, in the subway and in a sweater. Wherever we are, our smartphone is with us. Our friend, friend, love, confidant, who, like Sam from “The Lord of the Rings”, faithfully follows his Frodo, carrying his manatees. It combines our applications and our connection to the Internet, so that even in complete seclusion we are not helpless and left to our own devices. Unless there's no coverage. Then we are. But even then we can use the mobile application — admittedly probably without some of the functions, but nevertheless. Well, responsive website or app — that's the question!
