FT isn't a good sampling for BA or for any carrier as few come here to report that the IFE did function and the BA board is, of late, much more about how the world has gone to pot.

All of this does suggest that the more modern approach of not building the entire system into aircraft and rather moving towards streaming systems makes so much more sense. The built-in systems are expensive, heavy (weight matters), hard to repair, quickly dated, and less pleasant than streaming systems. Easy to install, repair (simply snap the defective system out and replace), update, people free to use their own device of choice, and carriers which wish to may provide (or rent) devices as they choose.

Today's state-of-the are in-seat system will be a dinosaur in 2 years. When it breaks, the decision to take the aircraft out-of-service to find a wiring fault is a major one.
