Same general trend on marine MFDs (basically the equivalent thing for boats). Models with knobs and buttons are the "premium" version, the default is typically just a giant touchscreen, which is not always great when you have wet hands. The flat screens look good, and work great in calm situations, but in heavy seas and/or rain, they can be challenging at times. In my case the manufacturer (Raymarine) offers a wired remote control, so I have a knobs-n-buttons controller that is easy to reach and offers more direct control when needed.
