This has nothing to do with TV addiction. It's all about convenience. Either you like it or you don't.
I would love to have it come as an option on the US-spec M3 but I highly doubt it. My wife's van has a Built in DVD player in the rear for the kids. When the parking brake is on the nav screen up front also displays the DVD. When I am waiting to pic someone up it gives you something to do kill the time. I think the OTA would be even better as you could check live weather ad traffic reports etc.
