Seems like I am in the minority in here as I watch the content on the IFE far more than anything on 3hr+ flights
Anything under 3hrs and it's probably 75% reading book 15% listening to music 10% part of movie or documentary.
I only use moving map for first 15 minutes or so of take-off, last 10minutes with landing, and I will periodically check in during the flight to see where we are and how much further.
