Wireless Internet on Airplanes

I spent a lot of time on airplanes this week traveling to Search Engine Strategies conference in Chicago.  While flying, the thought flew through my head "I wonder how much longer it is going to be before this flight is full of people banging away on their web browsers and using the Internet?"   Today I discovered that the answer to my question was "about seven days".  Apparently Jet Blue will be launching wireless internet this week and shortly thereafter it will be rolling to Virgin, Alaska, and American Airlines.  This will be an interesting test in human behavior.  I am sure a new list of decorum will now have to emerge about what is okay to do on an airplane.  The world is changing right before our eyes....
