WAAV’s AirBox CM3 can turn your car into a mobile WiFi unit. The broadband cellular router plugs into your car lighter by Ethernet or wirelessly and will keep the connection up to speeds of 100 mph or up to 300 feet when you are parked. Its 3G digital cell phone network seeks out EV-DO, which is comparable to cable Internet or DSL connection. If that fails, it will find an available 2G network. Available for $499.99,  you still have to pay for a data plan but at least you won’t have to seek out the nearest Starbucks when a communicative mood strikes you.
