Lawyers are prime targets for expensive boutique software.
After all, we have special needs that can only be met by software carefully written by the software elves with lawyers in mind. These specially crafted boutique programs almost always sell for premium prices. A software publisher will not likely sell anywhere near as many copies of a product written just for lawyers as it will sell copies of more generic products that do very similar things. Basic economics tell us that the larger your potential market the higher the volume of sales you can expect. The higher the volume of sales, the lower the per unit cost of producing the program the research, development, production, and advertising costs are parceled out over more copies of the program.
