Well you can forget about the company installing TVs in the seat backs as they just announced they are installing equipment on the planes to enable news, weather, sports updates and email only, (no internet) service to the inflight phones. All this for a nominal charge of about $15.00.
As far as the boarding music, that was one channel of the many we used to have. They pulled the music off all planes except the 767 and 330 over a year ago. I guess they didn't want to pay U2 and Madonna royalties anymore. 😉
