When and why did camera manufactures start putting electric motors in cameras to advance and rewind film. It just over complicates what previously was a more than adequate system with simple cogs and levers that could be serviced readily.
I could ask a similar question about autofocus c.f. manual...
The most common use for a motor drive would be action photography, in which the film can be advanced far more rapidly with a motor, while firing the shutter in rapid succession, than it can be by hand.
In my own case, I have auto-winders attached to my Minolta X-570s because I am left-eyed and they allow me to advance the film without removing the camera from my eye. This really helps when bracketing exposure and when making subtle changes to framing of the image. They also add gripping surface, as well as ballast to absorb a little shutter/mirror vibration and to keep the camera hanging vertically with a heavier lens.
