alt Hacker NewsYeah I guess I should correct and say that I do use an HP 50G emulator on my iPhone cuz I like RPN.
But even still, the iPhone can do many things and is many times more capable, and you can buy a used iPhone 12 that works fine for about the same price as one of these calculators.
HP 48G(X) is the OG and what I took SAT-I and AP Calculus BC exams with. The iOS/iPadOS emu app is called i48.
