As of 2017, Casio FX-9860GII. Overkill for actual usage, but cheap -- so why not?

Before that, TI-30XS from 2013 and the TI-36X from 2011. The 36X is still in my laptop bag. Can't remember what I had before 2011 -- some old "programmer's calculator" from the 90s.

My wife (and various colleagues) thinks I'm crazy, but it's actually easier to grab the calculator from the desk and do a quick calculation than to open/use the calculator app.

Makes sense to me!

It’s similar to how it’s easier to pick up a pen and start writing on a pad; then pick up your phone, open the note app and start a new note.

I just want a simple desktop calculator for the office. And that got me interested in the topic. But like you say, I t’s cheap enough to go for the overkill option these days.

The TI-36x is a solid choice for a fairly basic "scientific calculator" and is still widely available online (about $20). Mine is holding up well.

If you have the money for a "guilty pleasure", check out the HP 15c Collector's Edition. I might indulge myself.
