Sounds very like my work.

Yeah, schema changes are a pain in the arse, but I don't see that moving my code from views to models would have a great deal of impact (though I am gradually moving the code that way when it does need changed).

A better answer is, that you get to decouple the functionality of your application's business logic from the web portion. This is achieved trivially purely by applying disciplined coding standards. Removing the web dependency makes the code much much easier to write automated tests for, and it gives a sane development path when making minor or major changes to feature sets.
