I downloaded and used AC within 30 minutes. I had tried to use three other electronic records for years. AC is just intuitive and fits how I practice medicine. I am solo. I have a laptop in each exam room and a couple of desktops that I use for smooth efficient office hours. End of the day....the days work is done. No piles of charts. I have been using AC for a year and have upgraded twice and now I'm using V5.024. My husband who has no formal IT training is my tech guy. I have had no down time. I vote for AC.
