Comment Re:Still using my TI-85 (Score 1) 245
I'm a high school physics teacher, and I use my TI-85 every day. I've had that calculator since 1994, and it's the one calculator I never let the students borrow when they forget theirs. The kids laugh when they see the calculator and find out its as old as they are. Then, they are amazed, and a bit jealous, that it will do unit conversions and has the built in ability to solve polynomials.
