I disagree because you probably use the entertainment buttons more than anything. For instance, my wife's car has the volume control on the touchscreen, which is super annoying because it's something I like to manually adjust a lot.
I honestly can't think of what I would prefer be touch screen...really it should just display on a touch screen so I can use it if I want, but everything should be controllable through physical buttons too.
Touchscreen should just be for guidance. Maps, cameras, overlays, caller info, etc.
There shouldn't be any "entertainment" in it other than the radio info.
Touch screen should have maintenance/status display and diagnostics and settings for things you'd take care of while the vehicle isn't moving. Like seat/mirror positioning presets, ride height, towing mode, etc.
