Can someone (TightSlot?) define "electronic device" (as in "Please turn off all electronic devices now") for us.
I think it's pretty clear when you bear in mind that it's not just about the potential for interference to the aircraft's systems (very limited) but more about the need to concentrate on, or at least be aware of, what is going on. This means not listening to music through headphones, playing idiotic computer games (or sensible ones if there are any!), reading from Kindles, etc. Out of courtesy, I stop reading, even if I'm not really concentrating on the announcements.
