When the stewardess comes around and tells everyone to turn off their electronic devices, I just look around and laugh an evil laugh as all of these people with iPads and Nooks have to stop reading until we reach the right altitude. I, on the other hand, go on reading.
I use an ereader on planes all the time. I get that this is just a masturbatory rant, but can you imagine not understanding that you could turn wifi off? You generally want to anytime you aren’t downloading because it drastically impacts the battery life for the e-ink models.
