Oh very cool, I hadn't caught this amidst all the noise about Photoshop CS3. The drag-n-drop CSS management stuff seems kind of cool.
For me, though, Dreamweaver's just gotten a bit heavy. I still like certain things about it, but Textmate has become my best friend as of late. The one thing Dreamweaver has over Textmate is its CSS code-completion. Textmate feels a bit clunky in this area.
