I guess the "digital but with physical buttons" is the middleground. It still gives the designers the ability to mess around with acceleration curves that amplify fast movements, or to not sample the value fast enough to get coherent digital readings. I don't understand why they do this. As a university engineering student, I have a great love for linear systems, which usually is anything analogue. It makes everything easier. For example, the focus ring of a consumer digital camera lens drives me nuts, it's practically impossible to do a pull focus reliably between two objects. If you do it a little faster or slower, it will be off, regardless of the travel distance. On the other hand, professional cinema lenses usually have actual mechanical focus wheels attached to ensure perfect reproducibility.
