The other night I was standing on a crowded commuter train. As we swayed along I gradually realized that, of the four people in front of me, three were reading books (two text, one manga) and one was busy with a mobile phone. So I looked around the whole carriage and it seemed that, although the persons in my immediate vicinity were an unrepresentative sample, perhaps a quarter of the crowd had their noses in books while the rest were focused on a cellphone. There were even a couple of newspapers.
It seems to me that within recent memory, practically everyone awake on a train would be scrolling, swiping, pecking or poking at a little glass screen. Is paper and ink making a comeback?
