OOP != Inheritance. In fact, inheritance is to be used sparingly. Encapsulation and composition are more what OOP is about. Keep it simple and it will be maintainable.
We can go into detailed analysis of different features of OOP and what they advantages and disadvantages of each are, but I think that that is beyond the scope of this thread. Have seen people **** up in a spectacular way whatever they use.
Well said.
