Electronic bike shifting is a bad example here imo. You do have to stay on top of the charging (you get about 20 hours of riding out of a single charge), but aside from that the precision and consistency is waaaaaaay better than anything that had come before it, at least from my perspective. I used to have to adjust my derailleur every couple of rides on my mountain bike, but with electronic shifting I haven't had to adjust it in _years_.
The elimination of shift cables may (eventually) result in a simpler lighter setup as well. Could also allow some innovation in gear design if the shifts are computer controlled. We’ll see.
