I've rarely encountered anyone who uses more than 5% of the capabilities of a modern word processor (whitespace formatting is the industry norm and Notepad can handle that). I gave up trying to explain what "styles" are for.
Once in a great while I'll encounter a spreadsheet user that knows what they are doing (actually has a cell with a formula in it), usually in engineering or finance.
Presentations are an excuse for bad dialog (search for "Death by PowerPoint" for examples).
Access is an adequate DB IDE but the built-in engine (Jet, or whatever they call it now) is unreliable garbage, especially with multi-user DBs (SQL Server is substantially better) but I've only seen it used in larger business environments. Most small businesses use fixed-function applications specific to their industry or use a web-based online service. I've never seen a home user create a DB that wasn't related to a college class they were taking.
