My 2004 Fiat Stilo has dedicated buttons and no single touch screen. The "board computer" is a 5 "pages" menu that is able to adjust simple things like dashboard lighting and disable my door light, that's it. I never have to search for anything and, even more important, don't have to take my eyes off the road to adjust heating, radio, etc.
What's next? Touch screen gear shifting? Touch screen horn? It's dumb IMHO.
