Thanks to everyone who responded!

Although a little bit of bad news: I checked the PDA site today to see what my in-flight amenities are. If I'd flown this flight on Wednesday I would have had the full-blown new updates in the plane, DirectTV in each seat and all. Thursday would have at least had SOME in-flight entertainment with the drop-down TVs and the 12 audio channels. But the flight for Friday lists "Inflight Entertainment: Not offered on this flight".

Balls.
