I don't have much need for a calculator what I'm doing currently, but I have the same TI-84 from when I was a teenager, and when I had a desk I kept it on it. I find myself using the phone app calculator for most things "around the house" or for craft projects lately, but I am so irritated by it, it's not as easy to see the history if you made an error, and if you don't hit the enter key you get an answer but it doesn't commit that answer to history, meaning you need to do the whole calculation over again if you forgot to copy your answer or hit enter. And the reason I don't hit enter is because I still want to see my input operation, and hitting enter makes the output a new input more or less. On the TI-84 I can see everything conveniently laid out and more easily chose from my last outputs for new inputs. Never doing anything complicated, mostly just scaling ratios (how much material do I need for x size item), but it's irritating to have to do everything twice on a cell phone.
