What about the cost of all the object creation/manipulation that you don't need if you are just using it as data storage.

I downloaded your tutorial and I can't see where it says anything about the use of a hidden datagrid for data storage. I can imagine a very simple application being based around data storage in a visible datagrid but even then I would use custom property sets in an invisible stack saved in an appropriate place to get data to persist over multiple sessions.
