It's an option I would add to every non-sports car I would own from now on as it looks fresh and cool and when performance/sports feel is not a concern, any tech gadget is welcome. However I don't think digital screens have any place in performance cars, simply put, no needle no party. I actually was the "Playstation generation" back in the 90's so one could expect I would be all excited about digital dashes etc. but I think that the total flat screen, as the OP said, takes away a lot from the character of a performance car. I mean when I'm driving even something as humble as a GTI I don't need to watch the full map, weather updates or other crap on the driver dash, I'd rather have the red needles remind me in which car I am, there's always the main dash screen for everything else.
Exonian put it very well in that you might want to opt it only due to resale value purposes but personally it reminds me of playing Gran Turismo. And if there's one thing modern cars didn't need is even more fake (non-analog) stuff. I think a smart thing would be to keep the analog needles but have enough screen to play behind them and in-between, that could be best of both worlds if done properly but that totally flat thing currently in such cars is just wrong.
