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.
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.
