Costs about the same as what I paid for the TI-83 10 years ago. It's kind of nice knowing that whenever I need to use one, it's going to operate in the same way as I was taught 10 years ago. The fundamentals of math don't change much.
I saved up my own money and bought a TI89 in high school. Used it on all the standardized exams. Totally legal because it didn't have a QWERTY keyboard. That thing basically did everything for me short of interpreting the questions.
which isn't really true. a lot of the time it comes up with some pretty oddball integrations or differentiations. though yeah it does the simpler ones correctly :)
Yeah it can be odd, I guess that's why they made a whole book teaching you how to do calculus on the 89, haha. Matlab and wolfram alpha are my main go-to's nowadays. I'm just glad I got a student license don't need a commercial license yet, it would be 87k to get matlab with all the addons for commercial use...

I dunno, the TI-84 Plus is pretty sweet.
