I'm old enough to remember riding the bus before mp3 players and smart phones. Your only options were to read or to bring a CD player. Walkmans (Walkmen?) were a pain: batteries got expensive, and carrying more than 1 or 2 CDs was a pain, so you ended up listen to a few tracks over and over. Newspapers and books were good, but not as stimulating as the internet or email or Words With Friends. I still remember waiting for the train with no music, nothing to read, and nobody to talk to; it was excruciating.
Nowadays, I prefer transit to driving, even when it's a bit longer, because I can just zone out on my iPhone the whole way.
