I use an emulated scientific calculator Android app which has all the features of a physical calculator but none of the performance issues.
If I'm at my laptop, I usually just use a IPython REPL.

Re: Ask HN: Do you still use physical calculators?
#63I have a Swiss Micros DM42, a modern clone of the HP42s on my desk and I have the plus42/free42 app on pretty much every device I own. Stack based calculators are great because the stack works as a little scratchpad when I'm trying to figure something out. If I'm solving a problem of any complexity I'll move to a more appropriate tool like python or a spreadsheet, but for the simple math that needs to be done around…
SwissMicros calculators are absolute gem. Thanks.
They even have printed manual for DM32. https://www.swissmicros.com/product/user-manual-dm32

#64I still use my dad’s old HP 15C. Form factor is good, aesthetically it’s very appealing, it feels efficient to use, I like the tactile feel of the buttons, and I like thinking of my dad when I use it.
Re: Ask HN: Do you still use physical calculators?
#65Absolutely!
On my desk I have an HP-28S and use it nearly every day.
In the office I have a newer HP, which isn't quite as nice to use as the 28S but still quite good.
The ergonomics of these are so far superior to using software apps that there is no comparison.

#66Yes! I’ve held onto my TI84 from high school and find myself reaching for it far more than I ever expected.

#67My 30-year-old TI-83 from college is still chugging along. My kid uses it for school. Math homework is all pencil and paper so having a physical calculator is more convenient. It’s portable and dedicated to a single use that it does very well.
Re: Ask HN: Do you still use physical calculators?
#68Yep. College requires a TI-83 and I use a DM-16L for accounting homework.
Re: Ask HN: Do you still use physical calculators?
#69Yes. HP-11C. Who cares about the speed of the calculating device when I'm just adding or multiplying a few numbers? Physical buttons are easier to use than mousing on a screen. And it's highly portable.
