With the weather getting warmer and the days getting longer, I've got Summer travel on the brain. For me, travel often means sitting for hours on a plane, reading a book, or getting sucked into whatever movie is playing over the airplane's system. (Hey, next time I'm stuck on the tarmac, maybe I'll try Twittering with customer service [1] like our Cotorture [2] girls did!)

Now, some airlines have options for purchasing movies on flights, but when I asked you about it, most of you said you weren't sure you'd be buying [3]. So, what is your favorite way to entertain yourself on a flight?
