My biggest gripe with most OO tutorials/books/whatever is that the example is usually something trivial that fits into an OO model neatly, such as types of animals or geometric shapes. In the real world, you're likely to encounter data that is not so clear.

I agree. I worked hard to avoid using "a square ISA rectangle" type examples in my book. My primary OO example class is a logger called BOA::Logger for the fictitious Big Ol' Application. Instead of talking about inheritence as a way to express "natural" relationships, I tried to present it the way it's really used - as an extension mechanism to enhance an existing class. I also tried to give equal time to composition, an alternative to inheritence which often results in simpler code with equal or greater flexibility.
