Wifi on Flights

Alaska airlines has joined Virgin Airlines and American Airlines in testing wifi on some of its flights. Assuming it is successful, it could soon be on all flights.  The airline billed the addition as an improvement to the customer experience.  It'll be interesting to see if this eventually lead to cell phones on airlines.  Wifi is less intrusive, but it's reasonable that passengers may demand the service if the technology is available.
