I think styling did enter into this decision. I have a close friend who had Canon non AF equipment, and who wanted to move into a smaller and lighter SLR wirh AF ability. He decided on a Pentax MZ5-n. The decision was strongly influenced by the dials and controls on that camera - rotary, without LCD displays. The location of those controls was fairly traditional too.

I expect that there were a lot of Nikon owners who, when the FM3A was being designed, wanted to update their cameras, but who didn't want to change too much.
IMHO those Nikon owners had/ve good taste.
