PM software is all over the place. I use CollaborateMD and like it fine. It has its problems. I liked TotalMD as well. I had GE Centricity before and thought it was expensive, bulky, and actually can't do everything Collaborate can.
If AC is really coming out with a PM system, I would struggle by with something like Office Ally until we see if AC's is going to be worth a dang.
