That article is almost 6 months old, and in the developing world of IFE, it might as well be 5 years old. Look how far APS has come since its baggage handler days.
There is no reason that B/E could not incorporate the digEsystem into business class seating if the demand is there. Therefore, we keep abreast as things evolve. I saw no mention of the IFE offering, so it might not even be Wencor`s product.
So we watch and wait...but I appreciate you digging up the specific article...and I did note the business class exception in my first post.
