Hi Legal,
Good points. However, this is no different than meeting someone on your own in the gate area and deciding to sit next to each other. Seat Amigo and its connections Intrusive? You may be right.....you may be wrong. There are people that are loud anyway, intrusive anyway. If little ole Seat Amigo actually creates a ton of people yapping away on a flight.....then i guess that'll be a good problem to have. You are forgetting one thing. Seat Amigo also allows you to find someone quiet to sit next to.
Thanks for the input.
Rusty
