While not an early adopter, I did buy a cheap little MP3 player. Then I transferred my entire CD collection to MP3 format,
and put it on a microSD card in the player.
I'd only use it if I knew I'd be stuck somewhere bored out of my mind for hours.
There have been a couple of such occasions:
1. I spent a whole night at Waterloo Railway Station, in London, to be there for the first morning train to Paris.
The place is totally dead, with everything closed at night. Toilets closed, and not even a coffee machine.
2. Waiting for a ferry back from Cherbourg, France, for some hours.
I don't generally have my ears plugged in all the time, like youngsters do.
I prefer to look around and experience the place I am in.
In a car, or train, I like looking out of the window at everything.
