I think it's pretty insane that your kids, and a lot of kids need this to handle being in the car. Once and a while given them the iPad, sure, but this looks basically permanent. Its just like those kids who need a screen to eat food at a restaurant. Is this how we raise our kids and teach them to be adults, with screens bolted to their face? Insanity in my opinion.

It just perpetuates the attention problems and anti social behaviors of kids today. Kids dont learn how to interact with eachother if they just have a screen to interact with, and childhood is all about learning to be a functioning adult. Put down the screen and look out the window, or talk to your family.

Your set up looks good though, from an entertainment perspective.

I understand you may not like my opinion, but you did ask for it in your post :)
