No - or at least I don't think so! Views do this also.

I will send a View only example later, but the 'advantage' of having a
Model
is that it can support several different Views simultaneously.

Do you sometimes use "F2" to open a second Window on a source code file?
That is
one (useful) example.

A more sophisticated example might be that your 'Model' is some data,
and your
two Views are a Bar chart and a Pie chart, both giving different visual
representations,
maybe simultaneously, of the same information (ie the same Model).



Models provide extra flexibility that you do not always need. But since
using them is really
only a handful of short Methods I, personally, find it simpler to use
them. Then I do not have
to worry about two different design patterns, or worry that I (*might*)
want the flexibility later.
