I have been programming in C++ on and off for about 5 years, why have I never seen exceptions used other than examples for examples sake?
Observation bias at work here.
A significant fraction of C++ code is for systems programming and embedded systems. (After all, C++ is just one of many options for applications programming, and many of the alternatives have fancier RAD environments, but in systems work, it's often the highest level language for which a compiler is available, by a wide margin). And most embedded systems as well as a significant chunk of systems development work have constraints that rule out exceptions.
If because of your focus, you tend to search out this sort of code, it's entirely possible that the C++ code you've seen doesn't use exceptions.
That doesn't mean that there isn't C++ code using exceptions -- there is, and a lot of it. It may just not appear in code designed to solve problems that are interesting to you.
