The big question in my mind is "Yes, but what ELSE can you do with AMP?"  In a
single processor, the interaction between parallel paths is fixed.  The
programmer can do little or nothing about it.  But with separate processors, the
programmer has more options, or more flexibility.  [Or, at least, that's my
perception of the situation.]
