Buying albums on a cassette that you had to listen to all the way through, you had to either buy the whole cassette or not buy it at all, and there was no convenient option to skip the tracks you didn't care for the way you could on a CD or MP3 player. Needless to say just about every album had at least one track on it that was pretty lame.
Maps were kinda fun as well. You couldn't just navigate with Google Maps, you had a paper thing that folded up, eventually, if you were smart enough to figure out how to fold it. While navigating you had to negotiate creases in the map, moving from one side to the other (or one page to another, so you had to be able to flick through a book pretty quickly), and the way paper maps were inevitably out of date so sometimes you just had to take a best guess.
