Now You Can Use Your Cellphone While Driving
Not quite the most useful application, but over in Japan they’ve come up with a device to turn your mobile phone into a controller for a remote controlled car. This is clearly a pretty small niche system (though, you never know how fads are going to catch on), but I wonder if it’s the start of other companies starting to build “add-on” modules that turn your mobile phone into something entirely different.
