If I wanted to shoot like Ansel Adams did at his time, I would get a 10*8 view camera, hire a few horses and assistance, and schlepp my equipment up a mountain. But I don’t. Hence, when I buy a digital camera, I prefer it to offer the tools that make my life easier and allow me to get the shots I want to get. Hence, my search for IBIS, as something I am missing with the S. (I know my way around such as using a tripod or monopod but if I can do without these 2, so much the better).
I haven’t used the x2D and thus don’t know whether a joystick is something I would miss. Being able to have a histogram in the viewfinder is something I would like to have.
As to your comparison with cars, I had a Jaguar E-Type. Gorgeous car. Loved to drive it. But in order to get me from A to B in bad safely and comfortably every day much preferred a modern car.
