Here it comes "Never again use a Spreadsheet for designing power electronics"! I must admit that for work it is the best thing available,test scenarios, test components, circuit configurations everything numerical at a touch of a "button". But I don't need that, this is supposed to be for fun. I don't need speed of calculus, I want to keep learning the "Art". From now on calculations will be displayed scanned from the squared paper (I still have to find a scanner though)... And these two will have a bit more work...
Thinking back, how many times did I use a graphics calculator for a graphics problem? I don't remember, but not many...
I did love my HP48 in the last two years of university (before that I had a TI 57 II), I had to work for a while to pay for it and my father helped out with 50%.
Once at an exam, the teacher that saw my Texas classified it as "a Grocer's calculator", that was really embarrassing and this was in 1997!(most of my colleagues had either an 48S, the 48SX or the Casio Computer 850??)...
The HP32S was bought recently in Epay, to get something a bit more "portable" and keep "playing" outside...
