A while back I shook my head at Boeing's failed Connexion initiative.
I think companies that are thifty by nature (or even by design) understand cheap ways to test product ideas. JetBlue is taking a much smarter approach to putting Wifi in its planes: it's starting with one plane and providing a stripped down service.
The idea here is not to give users the best experience. The idea is to see how valuable the idea is. They can track how many people try to access the service and how often they do it. Given that current user's alternative is zero access to the Internet, I imagine anyone interested will be happy with a "better-than-nothing" offering.
And, if the idea doesn't have any wings (no pun intended), then JetBlue gets off cheap. And that's the point.
Good for you, JetBlue.
