Again, at the risk of sounding like a grouchy old man (which I suppose I am :P), when I'm chatting with my wife and kids, I have limited intetion of interrupting that conversation to turn on the lights or seat warmer or wipers or change a song :-/. And even when alone - the amount of time and subconscious effort to hit a button, vs converse with the computer... Honestly - these shouldn't be "either or". Sure, have a screen and voice for those who prefer - but leave a button or six for us ol' timers :-)
