The 737's mps-Atlanta and back were new and had monitors in the seat backs. I'm too cheap to by a movie, and too cheap to by headphones, heaven forbid I'd stand up and get my ear buds out of the computer bag, but they did have flight tracker. It is like watching your Garmin map, and it gave flight information. 30,000 feet +/-, 500 mph +/-, 157 +/- headwind (on the way home), and pretty consistent -58 F. It is amazing how little the items fluctuate. The really interesting thing was to listen to the engines whine, and as the pitch went up and down the ground speed would fluctuate a little, but the wind speeds and directions would be jumping all over the place.
