I have tried todomatrix about 5 times in the last 18 months in my quest for a replacement for the palm app Agendus. While it had a lot of nice features, there was not a 'killer' app functionality to it for me......until now. I downloaded the latest version and the "Inject into" function is great. This is what I was looking for, the ability to take someones contact information as the source and create a todo, a phone call reminder, etc with the address database being the source. I am now ready to purchase it.
