Delta will be offering internet service soon for it's flying passengers, making all that pesky sleep and readin time much more productive. I think it's great that technology is finally catching up to what we expect it to do.
On the other hand, what will happen when a passenger starts looking at websites that offend their fellow passenger, or airline employees? Will it be banned, blocked or censored by the airline, although a customer is paying for the right to access whatever content they desire on the internet? Although most people would find it embarrasing to access pornographic websites in public, at some point someone will do so if only to test the system.
