I go back to Alan Kay's vision of a Dynabook: A�personal�computer for children of all ages. It should contain all its owner's��personaldata, including� his or her�personal�programs, as they evolve through the years.� Continuity is a must; the owner shall never loose data.�
Do you really expect that the dynabook will be 100% backward compatible to Smalltalk-80?�

The essence of object orientation is
that objects collaborate� to achieve a
goal.
