I have recently started to use the demo version of this and it looks very promising. I can't work out though why it is so expensive, is it because it is a niche market and the volume of sales are therefore low? Is it because it's a specialist market that is wealthy and therefore they can charge what they like? It seems a pretty simple program so It can't have taken that long to code, maybe I'm wrong, any programmers out there care to put me right? Thoughts?
