That was the word that came to my mind when I read about this news earlier today. I've longed for the day where WiFi is available for long flights or even bus and trains. I believe productivity will increase as a result and flight anxiety can be reduced as travelers can now have a whole new cyberworld to focus on during boring flights.
The cost will be around $10-12 depends on the flight duration which is nothing compared to all the ridiculous airline fees we are being charged now days. The service is said to be available by middle of 2009.
