I understand the basic differences between tasks and calendar items, but I am
having a difficult time understanding the how they should be used differently
in the real world.  For example, we run a medical practice and one of our
employees needs to call 10 patients on a certain day -- not at any specific
time, but on that day.  What are the implications of making these "tasks"
calendar items.  I guess the heart of my question is, what is the best way to
standardize the usage of these tools.
