I would think anybody from the fifties would be absolutely shocked if you gave them a tablet with an internet connection and showed them how to use it. They could access any newspapers, books, songs, movies from any time, all the information they ever needed, all their friends whereabouts and actions, and could contact them instantly with text, voice or audio. Learn new things or just play fun games. Look at the map of the earth with street views from all around the globe. Even pictures from the surface of mars. And on the more disturbing side they could look up any sick violence or sex stuff to their hearts desire... Yes it's "kind of incremental" but my god, all this in a device the size of a clipboard pulling stuff out of thin air. Now that's magic, no other word for it. And this is just a tablet. Plenty more amazing "incremental" improvements. Put this time traveller in a tesla and push the pedal down. No sound and instant acceleration...
