Definitely agreed on keeping view-related things in the view, but IMHO you really want to (as much as possible without breaking the layer abstractions) put as much as you possibly can into the Model layer.

Think of it this way: the Model layer *is* your application, in an abstract sense. It is your application without any regard for specific output formats or input methods. So if part of your application involves generating summary reports of database data, there probably should be a model class/method which handles report generation.

However, it should only generate the report data based on abstract input parameters, and not deal with any user parameter input or user output formatting. An appropriate controller would gather user report parameter input from an HTML form or an emailed form (or a voice-prompt UI over a telephone), and an appropriate View would transform the report data into HTML or PDF (or text to speech) or whatever output flavor of the month.
