rmc, i'm always amazed by how little you aviation guys know about computers and telecoms
you know a bazillion of very difficult things then stumble on the very basics .. never mind, it's quickly said.
wi-fi is what sets us free of these damned network cables.
It is what these people are using when they sit waiting to board, and now it works on the airplane too. With it you automatically have a phone because of somethign called skype, so we can envision anyone willing to spend $9.95 happily chatting away his trip.
I think it's the greatest invention after butter on the sliced bread.
