The worst example for me is the volume knob on the radio in my car. When I start it in the morning I often find out that I was listening to something too loud last time I drove and I fruitlessly spin the knob for the ten seconds it takes for the radio to finish booting. I think the digital version of the volume knob is a serious downgrade from the old analog version. It's probably cheaper though. The manufacturer saves $10 and I spend the next 5 years swearing at my car right after starting it.
