I suspect that there's possibly a generational thing going on here.
Younger people are much more used to absorbing information which is presented in a Digital format - indeed, many of them are unable to read the time on an analogue watch or clock. There is also a (possibly spurious) illusion of greater accuracy - a Digital display may say (for example) 63mph, whereas an Analogue dial will at best be somewhere between 60 and 65.
(I'm no spring chicken, but I'm firmly in the Digital camp. When driving a car with both displays, I never look at the Analogue display).
