I like the flight map, but IFE is not a deal-breaker for me. I have a book, my own mp3 player, don't usually care what is showing for a movie. My *complaint* about IFE is the touch-screen and lack of knowledge on the part of the general public about how hard a touch-screen should be touched.
Too many flights have been taken with someone who thinks it should be poked and pushed instead of touched.

When I'm trying to sleep, that poke between movies can be a real pain.
