UDF's are useful if somewhat tricky. Dinesh uses a common scenario where you have a self referencing table (the common example is an employees table where each employee has a managerid that links to another employee in the same table) to illustrate how a UDF can make querying easier, how to use it as the basis of a computed column, and how to index that column.
