Yea, I forgot about the calculators. I had a Bowmar Brain bought in 1973
that was banned from my Algegra class. And I know that the first Hewlett
Packard scientific calculators was introduced a couple of years prior to
that. So 1970 seems like a good bet for the commercial introduction
time-frame.

I don't know about cameras. I know the Rollei 35 LED appeared in 1978, and
the Canon A-1 in the early 80's.
Hand held calculators made their first commercial appearance, i.e. Bowmar
"Brain", Texas Instrument SR - 8 or 9 around 1972.
