I hope Jon Bertman can see Ketan's comments as very important. Amazing Charts as an EMR is at a crossroads.
Most of us who frequent the boards will weather AC's quirks and work-arounds. But the growing number of new users (driven to adopt an EMR by the incentives) are going to be easily frustrated by AC's limitations and lack of clear documentation. I don't think most of us would spend several thousand dollars on software that makes our job harder (not saying this is true of AC, but it has some rough edges).
The way to leave users with a feeling that AC is above the rest, despite some limits, is with superb customer service. The little things that Ketan mentions, such as receiving a response, even if negative, gives one a feeling that the problems will be addressed, even if its a week, a month, a year.
I hope that 5.1 squashes a lot of bugs, my life will be easier. But even better if 5.11, 5.12 and so on show an increasing commitment to quality, and responsiveness to user comments. Most of the recent updates have been all about features needed to meet government mandates.
