MVC is great for managing the display layer, but it doesn't really cover how to manage your domain logic. IME, MVC scales best when the "model" is a logicless DTO created by a business layer. For small scale apps this is overkill, and you can squash persistence and business logic into the model. But for some complex apps you really benefit from a multi-layer approach.
