It's interesting to read the ongoing discussion here. I do wonder if, in a few years, someone will undertake some op analysis and the results of which show some unintended consequences of using an electronic system.
I always break out in a wry smile when I see one of the categories for the assessment of 'Day to Day Safety Measures' at my unit; the use of 'Tactile Methods to retain situational awareness'. Rather difficult on an electronic system.
