I make extensive use of dated tasks in Outlook. I do not use the calendar to view them. I have my "To-Do Bar" set to show only tasks that are due today and ones past due (all of my next actions). A task gets a start/due date on the day I enter it into Outlook (for me start=due date) with the default being today unless I know I don't want to work on it right away and then I give it a date in the future. I also use the flags in 2007 to defer tasks to the next day or week.
I have many tasks that recur on a daily or weekly basis. These appear in the the "To-Do Bar" on the day they need to be done. For example, "draft weekly report" appears on Thursday and "submit weekly report" appears on Friday.
I have a custom view called "future tasks" that shows all of my tasks which I review during my weekly review.
