Everything will undoubtedly feel nice/premium as a result of being metal and glass, but you spend more time looking at the entire interior than touching every part of it, so appearance is important.
Car interiors are static so your brain very quickly ignores it while driving or after owning the car for a while.
The interface / ergonomics on the other hand end up way more important than anything else when it comes to personal enjoyment of the interior.
For things like volume, A/C, adjusting mirrors and seats, I really, really want physical buttons. Not sure what I will do after my old Volvo dies, maybe the touchscreen mania will have gone away by then and physical buttons will be back. I can't imagine myself touching a screen while driving, I don't even know how I would be able to do that.
