I think for me the biggest bennifit of prenatal appts was to get to know my midwife. With my second child, when I went to an appointment, we generally talked for a good 45 minutes in a casual way. She would ask if I had any questions and point out things to think about in case I hadn't. Then she listen to the heartbeat and feel my uterus, but that never took more than 5 minutes. I always left the appointments wondering where the time had gone, and by the time I gave birth I was totally comfortable with her. I think it helped a lot beacuase it felt like having a truly caring friend there to help me.
