I don't know about you, but I've always regarded the
transistor radio as a perfect inhabitant of Future Past. Sure, it's horrible. It's an ugly little plastic box, reception is terrible, the tiny speaker is painful to listen to and the programming is enough to drive you 'round the twist, but it's also a remarkable invention that suddenly puts contact with the entire world in the palm of your hand.
If you want a real image of progress, it's a Masai warrior listening to pop tunes on his tranny.
