I have a sneaking suspicion that for all the worthiness of the principle of separation of concerns, it's impossible to completely decouple presentation and logic -- you're going to either end up having some degree of model-related logic bubble up into the view, or you're going to have some kind of presentation-related logic seep down into the view. What we've generally done as an industry is accept the former, but I'm not sure whether one is better than the other.
