A lot of my after hours time is spent improving my XML DOM object skills.
However, when I looked over my projects at work, I realized CSV file formats are probably more important than XML. Why? Because engineers like to use Excel. It seems to be the most important adhoc analysis tool used in our industry. Long before our statistical analysis tools are unleashed, rough calculations are derived in Excel.

We are using XML format to persist data for a variety of customer requirements. We probably should have used SQL Server mobile or compact edition, but we didn't.
Beware of using the DataGridView until you examine application performance with realistic data.
