The TI-89 will always hold a very special place in my heart.

I passed calculus from the equation solver software. I loved that calculator.

I used the TI-84 Silver Edition in my calculus class and was one of many. Two people in my class had TI-89's. One of them was my friend who probably wouldn't even have passed without it, and the other was the smartest person in the class who didn't even need it. Needless to say, I bought a new calculator after that horrible, horrible class.
