More on the HP 12c Platinum - Calculator blog - The Calculator Store

I am really impressed with the hp12c Platinum. The units I had been using in the past had clearly a lower quality with respect to the plain hp12c. As I said in the previous blog issue, this is not the case at all. I has been fabricated in the same plant as the other, it shares the same moulds and key mechanisms, and the only difference are the key colors (much more brilliant than the subdued and professional 12c) and the screen (where the numbers are taller and thinner). I have not run any speed comparison with the 12c. I have not taken with me any plain 12c for the weekend, just my trusty 15c, which is 40% slower than the very fast 12c; and tomorrow morning I will make a very simpler program, that I will let run for a couple of minutes, in order to see how far it counts. Initial tests finding the Interest rate in a TVM problem (which is inherently an iterative process) show that the platinum is indeed an order of magnitude slower than the 12c - at least for that task. There are several companions in the office that know about my weakness for calculators, and that would like to have a classy one. While the 10bII is fine, much better when it comes to aspect than the 20b and even the 30b, it is no match for a Voyager or a HP17bII when it comes to aspect. But the 17bii, although being the better calculator, is bulky and not so classy. So my companions would like to have a 12c, but are put off by RPN. When they have seen the Platinum, and seen that they may use their (slow, primitive) algebraic entry method, they want one. I don
