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

HP35S when I am explaining homework, backwards, to my kids and checking the odd invoice The kids have CASIO FX-991EX which is really nice (but forwards) and pretty much standardised at school. (Had to add a quadratic solver program to the HP35S to compete with the FX-991EX) PS I have also have a WP 34S knocking about but can never remember how to use it! |

My trusty HP-15C is always on hand. I don't use it every day, but at least a couple of times a week. It turns on in a second and always provides the correct answer, depending on the user :) During my engineering studies at university i learned to appreciate RPN. And my HP-15C hasn't failed me yet (it has it's second set of button cells since 15 years). |

I've had my HP15-C calculator for about 35 years and I still use it daily. I have an emulator on my phone, but the calculator is much more fun to use. One corner of the display is showing some creeping black pixel crud, so I really ought to find an ebay replacement. I can't recall the last time I changed the batteries, but it's been decades. |
| Sal Ammoniac:
Yep. I've always been an HP man. RPN rulz! Still have my ancient HP-65, HP-25, HP-41C, etc. |
| vwestlife:
Yes, and I am amused by how many calculators that appear to be solar-powered actually have fake solar cells in them! |
