| Do you still use stand-alone ("pocket") calculators? |

I use spreadsheets now because all my engineering formulas are also stored in them. Example is the voltage divider equation- I have the four variables isolated and can solve for Vin, Vout, R1 or R2, and calculate resistor power dissipation - all at once. |

I have an HP-42s that I don't use anymore. I also have an HP-25 that has not been powered up in many years due to a failed battery that is corroded in place. On Windows, I use Excalibur that I've always really liked: https://www.hpcalc.org/details/3650 On my Android phone, I prefer Free42 over RealCalc since it is essentially identical to my HP-42. |

I regularly use an HP-50g and before that regularly used an HP-48g. I also have a solar TI-35. A phone just does not compare in ease of use. A touch screen does not make up for a good calculator keyboard and the battery life is terrible in comparison. |

I still regularly use my HP 15C. Very nice layout, feel, and has a fantastic display. I also use a HP 42s. I prefer the 42s if I need to work with complex numbers. I have an HP Prime, which is also a good calculator but I honestly rarely use it. Obviously I prefer RPN format... I use Free42 (42s emulator) on my phone if out and about. PCalc "42" is also an excellent phone calculator that you can use RPN on. |
| SolarMan:
Yes absolutely! Even when I'm sitting in front of my computer and have a smartphone in my pocket I still prefer to use a physical calculator. I often find myself punching numbers into my calculator while doing reseach on my computer |
