Hi David,

One point of clarification, your post implies that DynamicModule and
Manipulate provide overlapping functionality.  They do not.  In very
basic terms:
 -- Manipulate is a relatively quick and easy way to create Dynamic
objects and to create an interactive interface.
 -- DynamicModule is a way of localizing symbols and data to an object
in a notebook.

So, Manipulate and DynamicModule do not provide overlapping
functionality.  In fact, often you might want to use a Manipulate
inside a DynamicModule.  See the Mathematica Demonstrations websites
for many examples of exactly this.

In your example, the DynamicModule command could be eliminated and
you'd still have something that works like a Manipulate.  The
DynamicModule wrapper simply allows the a1 and a2 symbols to be
localized and stored in the DynamicModule object rather than in the
session.  What this means is that, with the DynamicModule, you could
quit your kernel and still interact with the output.  This is very
useful if you want to create an application for other users, but want
to limit their exposure to Mathematica code.  You can create a
DynamicModule and then give them a notebook with only the one output
cell that contains the DynamicModule.

Hope that helps,
Januk
