I see your 7" touchscreen and raise you...
A 17" touch screen AIO dash (found on the upcoming Tesla cars):
I've seen pictures of this thing before, but never a video. I guess it seems kinda cool, but I think it's overkill. Anyone who's seen a laptop in a car at night knows how bright and distracting a giant screen can be, night mode or not. Also from an interface point of view, I can tell I'd be pretty annoyed at setting climate control and stuff through the screen -- I really feel that there are some controls that should remain tactile. That being said, I'm stoked to see what future app devs do with 17" of screen real estate.
