True, except when you have to write unit tests for an app where everything is extremely coupled and has 0 tests, which is exactly where I'm at right now :(

Agree. This is much more difficult with a spaghetti/legacy project :)

The other dilemma is while the developer may want to refactor something - that time/cost has to be factored in somewhere and often it's a difficult to sell to the client: 'if it ain't broke don't fix it...'
