The difference between the two of them is that the "Handlers" example is rather slow when the list is very large while the "Delegation" example can be extended as much as you want to without adding more overhead. The latter example is also a lot easier to change. Try the following button to dynamically add another list item with a nested list to each of them (this is done by changing the innerHTML property and appending a string - much like you'd do it with an Ajax call were you to use AHAH).
