I still don't know what the big deal is, in a classroom my 85 (with EL) is
just as visible as any other calc.  The only time I EVER notice it being hard
to see is in really low light conditions (ie 1 50W light bulb 10' behind me
as the only light), but that would be similar for any TI  I would think.  And
if that happens I just turn on the EL.  I don't have anything extra added or
taken off (ie plastic cover)
BTW. How are the new EL auto-on plans coming?
