I have one 15C that belonged to my grandpa and another that belonged to my dad. Alas, I wonder what fantastic piece of technology will I hand down the line!

I had that 20S for years. Great calculator. Display went bad so I got rid of it. I wish I’d explored fixing it instead.

In spite of having no shortage of calculator apps at my disposal, I missed having a physical calculator so I actually bought a NumWorks calculator a couple of years ago. It’s a great calculator but there’s just something about that HP calculator aesthetic that I miss.
