Good thing I didn't know that at the time. ;-)

The 28C was an invaluable tool during my grad school days in physics. I used it to calculate uncertainties on the fly and to do real time adjustments to measurements to take into account the decreasing strength of a radioactive source.

When I started teaching, I was the only person in the school with a graphing calculator.

I wouldn't want to use it today, but I sure did like using it at the time.
