I personally think that while the service is viable, the customers that would potentially use such a system would rather spend that time in flight not really worrying about doing any work or if they do some work while in flight, they want to be in a "bubble of seclusion" so that their office cannot reach them until they get to their destination. Inflight internet for the most part is directed towards the business traveler. One of the reasons why inflight internet access hasn't done too well is the expense of such a service. You think some hotels rip people off to use the hotel's wi-fi or high-speed connections, those rates are down right cheap in comparison to what the airlines charged (In many cases the price for either service is the same but when you factor in the time you get to use the service, the airline price is more expensive per minute). I think the general consensus (even with leisure travelers) is that "I'm traveling, I don't want to be bothered by things back home or at the office while I'm flying". Someone traveling on vacation probably would rather wait until they go to their destination (or until they got back from vacation) before checking their email. With airline IFE systems getting more of and more packed with bells and whistles, internet access is probably a ways away from being a standard feature in the majority of airlines' IFE systems. While the Internet has become almost fully ingrained into everyday life, there will still be situations and times where it won't be fully part of an experience.
