Really interresting. Last time I taked a plane from "United airlines", they had a "On demand" system with a touchscreen. I watched "The Big Bang Theory" and "Dexter" on the plane for free.
The flight seem short and I really enjoy that.
Open the GPRS seem on the same kind of "add value" for enjoy your ride.
For the price, I do a 5 days cruise to Tamba, FL / Mexico / Tampa, FL. On that boat, they charge $1.99 per minute. The $1.60 per minute seem cheap to me (for a begin). This only could become cheaper with popularity.
