Really? I ditched my newer calculators, and my HP67 is the only calculator I use now. If I need more power, I use a computer. -Chuck Harris

My first was a Ti-57 and spent many a happy hour writing things to fit 50 program steps. It had no means of storage so I had to type them in each time I wanted to run a program. The next was a HP65 that I love dearly and still have that to this very day. You'd have to prise it from my cold dead hands but it sits in a draw and others have taken the day to day work. I've been playing with Plotter.exe and it's a very fine tool. I can see it being very useful in the future for me.
