I definitely prefer knob and large button like those from a 2007, 2008 base model family sedan without a screen. But some times you need touch screen for this or that kind of extra feature. So my personal favorite system so far are iDrive and the new mazda system which let you control functions on a screen with a button/knob and preserve temp and volume control as separate knobs. BTW the worst system I've used are the ones which don't have usable physical button and doesn't let you complete your task fast in the touch screen. Yes I'm talking about you, Ford and Cadillac. And Mercedes, it's 2015 and you still have a dial pad in the center console, what's going on?
