I have been on one of those planes and the seats were too little. Everybody had a little flat screen that you can play games, watch cameras outside of
the plane, watch the newest movies in 5 languages and where the plane is. There is these "remotes" on the seats, but they are corded.
I was on a China Airlines A340. It wasn't a bad setup. They had pretty comfortable seats on it. Nothing spectacular, but it wasn't a cattle car
either.
