Queenslanders will be waiting a while for Wi-Fi on trains, and now Adelaide has stolen a jump on BrisVegas, rolling out a bus which includes free Wi-Fi services for all the passengers.
As with most of these projects, the connectivity on the i-Commute bus, which running for a six-month trial, is largely designed to provide passenger information and increased security. However, the Internet connection (courtesy of Adam Internet) will also be available for use by any mobile or PC-toting passengers.
I've done a little testing of using wireless broadband on buses in Adelaide (you have to do something on the way from the airport to town), and the experience has been OK -- though like any transport-based system, there are bound to be dropouts in the inevitable black spots.
Hopefully this will extend to more than one bus (though I sadly doubt it'll ever make it to the almost-moribund Adelaide train system, much as I love it). As Nick remarks over at Gizmodo, it might almost be worth moving to Adelaide for this degree of commitment to public Wi-Fi.
