Agree. I don't miss the buttons at all. My Chevy Volt had so many, all in a very confusing array, that it was sometimes dangerous trying to find the right one while driving. Not so with Model S.
Agree completely. When I went from my Volt to the MS, I was concerned about the touch screen ergonomics. While the Volt has a 'touch' console, the layout is ridiculous (such as the prominent/dedicated button just to set the time/date). The Tesla designers have done a commendable job optimizing the layout, and the static climate controls are well positioned. I do think they can improve in some areas, maybe more audible/haptic type feedback.
That said, there is still something to be said for being able to _blindly_ reach for a knob/button.
