I still haul my HP 11c out of the desk drawer for this and that. Heck, Wolfram Alpha knows how to understand the command "integral sec3x dx."Īlternatives there may be, but I, as you may have detected, like the calculator application for sentimental reasons. When it's time for me to crunch some numbers, my computers and phone already have serviceable calculator applications spreadsheet software will probably let me do something more useful with the numbers if they actually are important to me and Google, Yahoo, and Bing will all do some math. With all the alternatives to pocket calculators, HP's line is probably as endangered a species today as the mechanical slide rules became decades ago when HP's first pocket-sized electronic calculator, the HP-35, arrived in 1972. I find the app prices high, and it's annoying the 15c costs twice the price of the 12c, but I guess HP is considering that a used 15c costs between $66 and $289 right now on eBay the models aren't for sale new anymore. With software-once it's developed-HP gets to sell it over and over for much less extra cost. The 12c new costs $80 in its physical incarnation, but HP must pay the cost of making each one. Second, software comes with famously plump profit margins compared with hardware, even when you have to share a cut with Apple. Of course, they're a lot more likely to have their mobile phones with them than their calculators, no matter how pocketable they are, if indeed they still have the calculator at all. The software versions of HP calculators, announced Thursday, are clever applications for HP to sell for a number of reasons.įirst, HP attracted a lot of engineers, scientists, real estate agents, and Wall Street brokers with its calculators in years gone by, and the tool is genuinely useful still to those folks. In vertical orientation, the calculator app shows a basic set of functions. The $14.99 application is accompanied by a $29.99 emulator of the 15c scientific calculator, which is better at handling trigonometry and integration than mortgage payments and net present value.Īll that's missing is the pocket protector-like iPhone case, my colleague Ina Fried cracked as she mocked my nerdish tendencies. That's because my three-year-old son, an iPhone fan in his own preschool way, is about to be exposed to Hewlett-Packard's new iPhone application that fully emulates the company's 12c financial calculator. As this calculator is regarded amongst the very good in terms of quality, key stroke feel and daily usability for engineers.It looks like a fourth generation of my family is going to be introduced to the ways of reverse Polish notation calculators. The production of the 31E ended in 1980, production of the other Spice models ended in 1983. The HP-33E/C (49 steps plus subroutines) and HP-34C (70 steps) and 38E/C (99 steps) are programmable, the C-models have a permanent memory. The battery of these calculators can be changed without using tools. The HP-37E and 38E/C were the financial models of the Spice series. The entry-level was the HP-31E and 32E, that were not programmable but even the 31E provided a Self-check. The display provided better readability by increasing the digit size and adding commas. Perhaps the HP-30 series, Spice, was to be released as a replacement for the aging HP-20 series.
