Most powerful sun position tool available

Read a few of the previous less favorable reviews with some concern. I have used Helios on a number of shoots now and just dont see any validity in the criticisms. I cant really see how this application could be improved. Its accurate and once you get to grips with it, easy to use. For someone who has spent the last ten years location scouting with a Suunto Tandem and a Sunpath print out, this is a major improvement.
