I really hope cars don't go into this one ecosystem deal with Microsoft or Apple or Google. I hope that all the car companies go with a common software plugin that allows for any phone to connect via miracast (or something like it), that way any phone can be used with the entertainment system.
If a car is strictly iOS or Android or Windows, I will be less likely to buy it, unless I can have the car come without the preinstalled crapware. A2DP is all I need.
