Ford just announced the support for Android and Blackberry Applications.
This is kinda cool. I can envision some pretty sweet applications if the auto manufactures allow it. Imagine running the same application between your phone and your car. Perhaps we can have streaming of music from our home collection using Windows 7's media streaming feature in Windows Media Player. Or perhaps the streamign feature in the next Windows Home Server.
Maybe even geeky stuff. Applications similar to that of our PCs that measure voltages on the different rails, temperatures and fan RPM speeds. Imagine some slick apps that could graph your engine temperature or gas mileage over time. All these geeky things could be a real possibility.
Cars have gotten quite complicated, complicated to the point that many cannot do their own auto work. But perhaps this could keep mechanics honest if all information is available to us. Who knows, it just sounds neat.
Hopefully there is not much market segmentation in the future. If all cars supported this (which wont happen soon), would you have to buy separate apps for your toyota, audi, and ford?
