I must be the unusual one ... even on very long haul flights, I very rarely use the IFE. Since I often have to work when I get off the plane, I eat, read, sleep, and read. I find it's a great chance to catch up on reading that I almost never get to do at home.

Disclaimer: I'm not really a movie guy, or a TV guy. And while I LOVE music, I'd rather read without music (although sometimes I'll have classical/chamber on in the background)
