There is no question that over-use of inheritance (failure to understand composition) is a classic beginner mistake.  That said, don't underestimate the value of inheritance.  Granted, the example I have in mind is perfect for specialization, but beyond that, failure to use (extensive) inheritance can at times lead to lots of duplicate code (which is really bad).  Say it once - inheritance can help one do just that (policy up, implementation down, etc.).
