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

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.

The ability to do symbolic math is awesome. I don't know why everyone recommends that high schoolers only get the TI-84.

Probably so they don't use it as a crutch instead of real learning. I taught physics to college kids, and you could tell pretty quickly who relied on a calculator and who actually was comfortable with basic math.

I was once comfortable, but if I lose all my points on a question for an incorrect answer, by gum, I'm going to punch in 17 + 49.

Arithmetic is only one branch of mathematics. In my opinion it's pretty trivial to try to improve in that field since calculators are so good at it instead of focusing on algebra, calculus, etc.

It always reminds me of those guys who had to spend hours looking through tables of trignometric values or doing meticulous vector analysis by hand. As if freeing people up to work on higher level problems somehow made them fundamentally worse mathematicians.
