(At the risk of getting way out of my depth:-) I would say another important
difference is that the languages semantics are defined directly in terms
of graph re-writing, rather than lambda calculus. Not that I really understand 
anything about formal semantics, but IMO from a programmers perspective this
is good thing because it allows programmers better control of sharing and to
distinguish between constants (CAFs) and "functions which take no arguments"
(both concepts being semantically meaningless in lambda calculus AFAIK).
