Adelaide Airport free WiFi

In my previous post (On Adelaide Airport, Embraer E-Jets) I almost forgot to mention the best thing about Adelaide Airport, shown above. Internode of course is one of Australia's largest ISPs and is based right here.

Which leads to the inevitable question: is it sad to have your life completely dependent on a computer network? Is it healthy? Should I be concerned? Should others be concerned? Can you get a brain ethernet implant or something? Perhaps I shouldn't be asking these questions!
