I've used and programmed an HP-15C, but it was a novelty even then, 22 years ago. I haven't used my HP-48GX since college. This reimagined 15C might be interesting if you could access the ARM CPU or there are extended features. I don't see any references to I/O though.
For practical interactive calculation I get a lot of use out of calc http://sourceforge.net/projects/calc/ http://sourceforge.net/projects/calc/. It's algebraic, but I find that less error prone than RPN.
- wyclif 15y agoNow that you mention it, the HP-48GX is another calculator that found a niche: land surveying. It's so popular in that particular line of work that you can barely get your hands on a used one on eBay. There are still third-party cards for COGO and data collection that surveyors and some civil engineering professionals rely on. I still have my HP-48GX from college along with the manual and it's a standard tool of the trade: http://www.johann-sandra.com/surveying/hp48gx-hp-48gx-48.htm http://www.johann-sandra.com/surveying/hp48gx-hp-48gx-48.htm
