We use satellite Internet connections in our office here in Ohio. Our downloads are quite fast (well over 500 kbps and as high as 1.4 Mbps) and it allows over 250 simultaneous users. Since web page downloads are fast and most people spend more time reading their screens and are not downloading (unless everyone on the plane is downloading music from Napster or something...eek!), the connections should be pretty fast. Also, consider that a lot of passengers will not bring notebooks on board because they do not own or travel with their notebooks...and, consider that most people are presently not using the power ports on the flights...many do not even know where the power ports are located. My conclusion is that it will take a lot of time for this to gain popularity...and there will be a lot of passengers who will not be able to justify the cost of the service, let alone have the equipment or the desire to use it at all. For those of us who want to use the service, it should work just fine...It will be nice to have an alternate diversion from the movie(s) or the in-flight entertainment. Personally, I am looking forward to this. Also, it will be interesting to read all of the in-flight critiques that will be developed from passengers who will be communicating with all of us on FlyerTalk.
