But maybe the metaphor isn't a good one anymore.

I've heard many people call them "radial buttons" because "radio 
buttons" doesn't mean anything to them (not that "radial buttons" is 
meaningful). I guess car radios and home stereos still have radio 
buttons, where you press one to unselect the previous selection and 
make the new one. But it's not like back in the early 70s, when you 
*knew* you were pressing a button because you could feel something 
happening. And as you say, the selected one remained pressed in. 
("Boy, when I was your age...")

I like having no radio buttons selected in a Web application, just to 
force an action when I want that.
