For example, I and others wrote a program for a local physiology center to analyze data for a typical kind of experiment. During two years of use, the physicians found so many ways to enhance the program that it is now reported as better than the commercial solutions. The total of all fees they paid during these years reveals the program to be more expensive in the end than some of the commercial alternatives. This fact is not relevant to my clients, as they have exactly what they want and they know they can have more should the need arise. The program is obviously Free Software and other centers expressed interest in getting a copy.
