low tech can provide control and persistence. I want a real hardware volume dial on my phones and laptops. Mostly so that I can turn them down and be sure that that I will not embarrass myself by making noises at events where silence is expected. And I miss DIP switches. It is just brilliant that you could configure it once and for all. E.g. I have smoke detectors that could all be linked together by pressing some buttons in a weird ritual, but when you change a battery they forget and run down the battery in no time trying in vain to sync.
