To simply state that the 85 is easier to use and program might be a
little off.  For a person that has become proficient at using the 81 and
knows its menu system the 82 might possibly be the choice to make.  With
the new CBL system that will work with all the 82's out here but not the
85's, from what I have read, a little more thought might be needed.  In
my use of the calculators I have not found the 85 to be as user friendly
as the 81-82.  As to the 81 being "out of date" this may be true if we
are talking the "cutting edge".  I still feel that the 81 is a great
teaching machine.  In solving systems of equations the calculator forces
the user to make choices in the solving process, the 85 solves them for
you.  This argument takes me back to when I first saw the TI-68, it was a
quantum leap from the 34.  But then I still use my "electronic slide
rule" TI-30 with its' 9v battery. (By the way it came with a belt loop
carry case).
