MCMS vs. Dreamweaver

Our company would like to develop a Web strategy around MCMS with hooks into Sharepoint Portal, our own Customer Care site, Professional Services, etc.

We are an ISV developing our own .NET product including a WebPortal product which seamlessly integrates with our offering.

From an asthetic point of view - We need a new website for several reasons, including:

Our public face should be consistent with our new corporate look and feel.
Our existing website is extremely simplistic, and does not adequately reflect who we are as a company or the sophistication of our product.
Modifying our current website in any real way presents technical challenges which no one internally is able to do with the exception of our developers on staff.
 

Our new website will be the public face. It will provide information to a variety of audiences, such as:

Prospective customers. This will be their first opportunity*, in some cases, to delve into the details of our company.
Microsoft employees looking for technical information about our product
Potential investors looking for information about Company
Press/other interested parties looking for general info about our Company and our products.
Providing the right information to the right visitors (and collecting the right information from the right people), in an easy-to-navigate environment.
Optimizing our site for search engine results.
Enabling our non-technical marketing staff to modify content on a regular basis; to create and delete pages for events; and to collect data from visitors.
Continuing to host our site internally
Ensuring that our technology environment is stable and secure.
Potentially creating the ability to link our website to our Microsoft Dynamics CRM database and provide online functionality including meeting/event registration.
 
Since we are an all Microsoft Shop, we have great synergies with MCMS with regards to Sharepoint integration, and our current Customer Care portal.

Now, the product that we choose needs to be easy enough for a non-developer to update the content on our Website.
For example: Webcasts, current news, etc.

The people that are developing our Website prototype is telling us that MCMS doesn't have the flexibility to allow for a non-developer to make changes, and that MCMS is challenging to work with... So they recommended "DreamWeaver" as the primary web platform.
 
I need to ask the experts and get your opinion -

Should we go with MCMS or Dreamweaver?

Or do we use MCMS with an additional tool that allows for updating our Web Content easily?

thanks all -
