Follow-up question to Anonymous's answer to How has the world changed since various Quora users were born?

I remember that when I was younger, my parents had as talk along these huge road atlases whenever we went anywhere. No more. First came Mapquest, and then Google Maps and GPS systems. Now you can get a GPS app on your phone. Similarly, I remember - although barely - the days when you actually had to leave your house to buy music. Nobody does that these days, except old people and hipsters. And quite a few people go without paying for music at all.
