Analog controls have a lot of physical feedback that a screen cannot mimic. Switches vs knobs. Some knobs are multi-detent switches. I can look at a radio, see the frequency, and know how many detents to get at or close to the desired new frequency while looking elsewhere because I can feel the increments happen, same for transponder codes, same for changing mode or view. And in turbulence and/or at night, or heavy workloads, it's even more handy. About the only replacement I can imagine being better is the Firefox (film/novel) interface. I'd even learn Russian just to have that interface. You must think in Russian.
