I think graphing calculators are great and I have learned alot from fooling around with them  but too much of a good thing can be deadly. I believe that calculators are overused in the entire school system and that students would be better mathmeticians if they had never seen a calculator.
If you understand math, you can quickly figure out how to manipulate a calculator. Unfortunately many of our students learn to manipulate a particular calculator and never learn the concepts.
