I've yet to get to play much with DW MX, I'll admit. I just don't like the feel of WYSIWYG tools. I have enough templates to churn out sites by playing in photoshop and changing the stylesheet a bit to be happy enough.
I'm also a firm believer in the idea that the client's needs should direct the form and style of the website -- who will maintain it, what tools are available on the server, who is the target audience.
I know, I'm an old, grumpy webguy, forgive me.
