Examples of using the Model class?

Not to belabor the point... But I just watched Derek Jones' "blog in 20 minutes" video tutorial and he put all the database-related functions right into the blog controller class and didn't even bother going into the model area at all.

And that certainly seemed convenient.

What I don't see is any benefit in the CI framework of doing what he did in the Model area instead, because the Model area really isn't doing anything "model-like" such as defining the database schema or anything, right?
