I took a moment to think about the questions I was just asked. "It's called a cellphone, a neat little thing we call an mp3 file, I don't know the specifics of that one, and… well, just about anything. With the press of a few buttons, you could reserve a table at your favorite restaurant, talk to someone from the opposite side of the world with your own voice, or send a letter to someone near instantaneously. Hell, that book I mentioned earlier? About two months ago, I used my phone to order both it and its sequel off of a service called Amazon and have it delivered right to my door."
