Airlines are doing this new fun trick where they interrupt your in-flight entertainment not only for the safety announcements, but also to play ads for their credit cards. And they'll turn up the brightness if it's turned down and turn up the volume if it's too low.

I do tend to mostly read on planes, but e-readers are nice because you can pack fifteen books into something the size of a couple of phones, and they can be backlit so you don't have to annoy your neighbor when they're trying to sleep. Back in the day I always had the problem of putting like three library books into my backpack and more into my checked bag, but I'd still finish them all before the return trip was over and be left without anything to read. With e-readers, I can check out new books mid trip, or even at the airport.
