I can do a whole heck of a lot to improve my situation with a smartphone. Some examples: navigation, gathering information, making/changing airline reservations, buying train tickets without a physical credit card, renting hotel rooms (reservation, check in, and in many cases “digital key” capability) without a physical credit card or indeed without interacting with a human, find and unlock the doors on my car, in some places pay for parking, and I’m sure I’m missing a lot.
