theodp writes "Cars.com's David Thomas speculates that the iPad could prove to be a serious problem for automakers that charge a ransom for rear entertainment systems. The base iPad, Thomas notes, costs far less than most DVD options offered by automakers. Ford charges $1,995 for a dual-headrest-mounted DVD system in its Flex crossover. In the Acura MDX, its single-screen system, with three wireless headsets and a 9-inch screen, costs $1,900. At $500 a pop, giving two kids their own iPads would cost far less than what the automakers charge for an ICE system. The Cars.com article mentions some of the advantages of ICE, including being weather-tested to work from -5 to 160 degrees F (-20 to 71 C), and being far less prone to breakage."
