I moved to this application from the paid Todo as a way to seamlessly sync my tasks via Exchange between all my devices AND my desktop Outlook. It discovered and configured quickly and there were no setup issues.
It lacks some features I liked in the regular Todo such as the popup menu on a task to change it and the default setting on a new task is to set no date rather than the start date but I can work around those. I dont feel the cost of the app was a problem it works and that is what I was after.
