With regard to all the Android angst in this thread, I expect you'll start to see some love from the various manufacturers over the next 12-18 months. In fact I also expect to see Windows Phone integration eventually as well (though certainly not before Windows 8 comes out). Right now WinPhone is a total joke (in terms of market share), but there is some smart money on WinPhone trending towards legitimate market share in 2013/2014.
There's no up side to a manufacturer restricting its customers to Apple products without any kind of monetary incentive from Apple, and the only reason we've had virtual iExclusivity thus far is that the luxury brands like to be out in front with tech options. With even cheap cars getting basic integration now, and the luxury makers wanting to push forward even further, broader integration options are an obvious direction to go.
