No sure about iPad integration, but more useful accessories are available, ... ie, scented diaper holder.
Yes that's just what I want in front of my kids in a crash, a heavy sheet of glass.

For more economical cars? Hell no, what 's the point? Not everyone have ipads and not everyone want their kids to use an ipad while in the car.Kids get too much distraction now a days anyhow. I'll never get a car with the DVD player etc. They can shut up enjoy the scenery and learn to be patient like I had to do when I was growing up LOL.
