When I started junior college in 1971, my Dad bought me a calculator. Prior to this I had, like every other nerd in my high school, done calculations on a slide rule. As I remember it, the calculator was a Texas Instruments, and it added, subtracted, multiplied, and divided. And it took square roots, which was a really big deal. Actually, now that I’ve spent some time digging around on the web looking for it, I think he must have gotten it for me in 1972, because TI didn’t make them until then. It appears that it was an early model in the SR-10 series.

Anyway, I remember that it cost $99, which is about $480 today, adjusted for inflation.

The other day I was buying a new printer/scanner/copier at Staples, and in a bowl on the counter by the cashier they had a bunch of little calculators on key chains. I realized that a) they had all the functions my original calculator had and b) they sold for 99 cents, exactly 1/100 the price.

I think this indicates that I am old.

    No, it just demonstrates the exponential growth of technology.

    I know. That’s part of why I think it’s so keen.

    It’s a well-traveled squirrel, I’ll grant you.
