This article is spot on. I am not even a fan of how the manufacturers switched from sliders and knobs on the HVAC controls to up/down buttons with a digital temperature reading. Does it really matter if you set the heat to 78 or 79? Most people I venture would be happy with all the way low, all the way high, and the midpoint. It's so much quicker and less distracting to be able to turn a knob for temperature to your desired level without even taking your eyes off the road. Up/down arrows with a readout require you to look at the current reading, then press the correct button a number of times, sometimes 20+ times to get your desired setting.
