In a word, objects are clever and widgets are dumb.
Widgets have an extremely basic interface (SET_VALUE
and GET_VALUE). Object widgets can be interacted with
in any number of clever and creative ways. Plus, an
added bonus, since they are so clever, they become
idea-generating machines. The biggest problem you
have with object-widgets is resisting the temptation
to make them TOO clever! You can do too many things
with them and you will find that you have to resist
tinkering with them and just get the basic job done
and move on. Otherwise, you will end up a geek
instead of a scientist.

Cheers,

David
