> Personally, I think information display can and should use touch interface, but actions should be tied to physical switches or buttons.
Underrated comment!
Information - the user is already looking at the screen, so they can touch virtual buttons. And that is probably the best approach, as they are manipulating information that is being displayed and they can see.
For actions, you won't necessarily have your attention on the screen. The information may not even be displayed in the screen yet, so now you have to divert attention and manipulate the system to get it to a state you can then change(eg, moving to the climate control screen).
