Connexion by Boeing and Singapore's StarHub connect network billing: It's been a dream of mine since I first heard about Connexion that the business traveler of tomorrow checks their email at home over Wi-Fi (using DSL backhaul), handles work in the back of the cab to the airport by 2.5G/3G, logs into the airport Wi-Fi network, and hops on the plane to use in-flight Wi-Fi--all with a single account. StarHub and Connexion's memo of understanding is the first step in seamless connectivity.
The kinds of business travelers who routinely fly distances that will be served by Connexion are the kind who want (and possibly need) continuous connectivity to keep their role in the business information flow active. This doesn't mean you want to sit next to them, on the plane, of course, especially once in-flight cellular becomes a reality.
