Thanks for pointing out that components can be used for many things.
My first reaction to Flash MX components was that they would be great for DESIGNERS who didn't want to program in ActionScript. I figured that designers would buy components the way they might buy plug-ins for other graphics apps like Photoshop and 3D Studio. In fact, I've gone on to create and market components targeted at designers- see http://methinks.com
Of course, I couldn't have done it without the help from Colin's wonderful books!
