- I use my HP Prime at work almost daily and I love that it has a touch screen where I can quickly copy paste past calculations. This in my opinion is better than using a stack calculator and RPN. There are also some small programs I wrote for like calculating parallel pairs for a given resistor value, based on E-Series since calculating resistors for stuff is quite a standard thing for your day as an hardware design engineer.
- I also have a Casio fx-991ES Plus which I bought during my student years and love to use it, because it is way faster for quick stuff than my Prime and I changed its battery in the past 10 years just once. This is not the case for Prime where I have to charge it every week or two. But doesn't bother me. Prime is an amazing calculator.
