Buy’s deal of the day is this HP 12C Financial Calculator. I’ve owned several and just between you and me I never had the slightest clue how to do anything but add or subtract on them. I always thought it made me look smart – so I carried it everywhere. If you need it for more than show this is the granddaddy of boss-impressing calculators. The HP’s 12c Platinum calculator is a natural for real estate, finance, accounting, economics, and business calculations. It features the HP 12c standard edition’s 130+ built-in functions and memory for 80 cash flows, complemented by a black and silver body, and embossed leather pouch. If you read the manual you’ll even learn how to program up to 400 steps and execute them with one push of a button. Over 130 built-in functions and two entry modes – RPN and algebraic. If you’re dad does anything remotely financial for his job – this is a great Father’s Day gift. Just writing this makes me feel smarter.

OK … RPN-geek mode in full swing …
The HP12C was actually introduced in ‘81, meaning that it has been in constant production for 28 years! Imagine that in an electronic device!
My first HP was a 41Cfrom the late 70’s, which I then sold to help pay for my Apple ][+ and bought a used 15C. I later got a 28C (which I still have) as a gift.
Still later I got a HP 48SX … which I can’t believe is now ~17 years old … but I still use it fairly frequently.
Also, the first thing I do for any PDA I’m going to use is put on a RPN-based HP Calc app.

And if you need a financial calculator but nothing that complicated…I am quite partial to my 12bII. (Currently I am held hostage to it while using it for various things, so my fondness may be stockholm syndrome. But still. It’s more calculator-ish, but still has some excellent higher functions.)

Wow does that bring back memories. I can’t believe they still make this model. Cool!

Like Wayne, I never learned how to do anything advanced on my HP 12C (though I could multiple and divide). Never the less, I was once hauled out of a midterm exam in a statistics class because the professor was convinced I had programed it with all manner of majic to ace the test. It didn’t take long for my cluelessness to shine through, thankfully, and I was allowed to go back and finish the exam, though her concern did plant an idea I employed for the final…bring a different calculator.

I use it almost everyday at work, even with a spreadsheet in front of me. I can’t use a regular calculator anymore… Very solid, will last forever. Great to determine loan payments, interest rates, etc. Spend 5 minutes just learning that and it is more than worth the money. Battery lasts forever.

There are also of wonderful HP 12C calculators for the iPhone … personally I love the recently released i41CX … just went with the standard, not the one with expansions and printing, as I never touch that stuff anymore on my HP48
