My partner and my staff love it as well, as does everyone else that I introduce it to. We have been using it for several years. We have a network version and it is constantly running and constantly in use on every machine in our office all day long. In a way, it is the heart of our business. It just keeps getting better and better.
Support is always excellent and the developers listen to suggestions for improvements.
I use Time and Chaos with the PilotSync add-on and my trusty palmpilot. This is an unbeatable combination. I think it is the best PIM on the market. It works like I work. It thinks like I think.
