I want something that can keep track of all the things I have to do. Something that monitors the various deadlines and priorities. It should be aware of what date is today and how much time certain tasks will take. Something that I can ask what should I do next and that will tell me what I should do next. It’s not a problem if I have to enter my tasks into it, but it should understand that getting a leaking pipe fixed will probably require me to call a plumber. Of course it would also be nice if it could pull tasks, for example from email or from the calendar.

Is there anything like that out there?
