I don't completely buy that argument - we still use hardware keyboards for laptop and desktop computers. Some hardware interfaces are just naturally superior. Humans are tactile beings, and if you want to operate an interface without looking at it, you need an interface that a person can feel. I have a Cadillac XTS, and it is a 100% touch interface. I cannot do anything with the radio/climate without taking my eyes off the road. I absolutely hate it. It doesn't respond well in the hot Texas summers, and requires more effort to operate than even the cheapest in-dash car UI. Contrast to my friend's Audi, which I can do most things with the center mounted dial without looking, just by memorizing how the console feels.
