    It is funny that you mention calculators.  When I graduated college (1998), I received, as an award, a HP 48GX.  It was a very complicated calculator, and much different from the TI-85 I had been using for 5 years.  It was the 1st calculator with a stack I'd seen, and I needed to look in the instructions just to figure out how to do basic arithmetic.   I bought, that summer, two cards; the first was a memory expansion card, and the second,  a program card that slid into the back that was for Celestial Navigation.  It was from Europe and was called Navigare or something to that effect.  While it worked, I never used the calculator enough to learn the syntax of the commands, so I have never brought it to sea with me.  I do use it at home every once in awhile however.  Still, mostly just basic math and sometimes Celnav.
    Sadly, my profession has not required calculators of that power, so I've never really done much with it, and used my trusty old TI for all of the math I've done for work, school, and testing. (Although I do use the Tamaya NC-2 for spherical triangles).
