alt Hacker NewsI sort of agree.
You're paying $100 for completely antiquated hardware where its core feature is "it doesn't do much".
Pretty much any professional environment that you will need calculations will have access to a computer that can do these calculations significantly faster and better.
I thought my HP was pretty cool in high school, but pretty much the moment I graduated I stopped using it because I figured out how to use Excel and/or a programming language to do number crunchy stuff. Even for CAS stuff, I would just use Wolfram Alpha or SageMath (depending on how ambitious I'm feeling with setting stuff up).
I can't remember the last time I used a calculator outside of showing someone else how to use it.

The interface is great for what it does though. I still use ti-83 interface with the calculator app on my phone.
Well I'd add to that - the real core feature is that the teacher and usually the textbook show you exactly how to use it, that's why it gets listed specifically as a course requirement.
That unfortunately is also why they can charge so much and people buy them anyway, because at best you'll be on your own to learn how to use anything else (and at worst you won't be allowed to use it at all for tests and such).
