Mike,

So, non-technical users...

 - Finding phone numbers for a particular range of exchanges in a large document and changing the area code.   
 - Reversing all names of a transcript (e.g.  lines start with <first> <last>: "quote" and become <last>, <first>: "quote").   
 - Finding every instance of an email address *not* followed by a particular domain name.   
 - Changing every date reference in a particular format to a different format (e.g. MM/dd/yy to yyyy.MM.dd) without affecting other numerical references (e.g. scores like 93/100, or 6/10).

Those could be needed by anyone, not just IT or Tech Services.

HTH.
