I've completely disabled Dashboard on my iBook. I can't see the advantage of it over standard desktop apps - especially given that they each use about 10MB of real RAM. Give me Calculator.app any day. Launches in a single bounce, and has a whole ton more functionality than the widget. Many if not most of the widgets don't take advantage of the ability to write Obj-C code, making them simple Javascript/HTML apps. Those things I'd rather look at in my browser window.
