I love this story, and it's sad to hear about companies abandoning features that users care a lot about such as RPN.
Personally I think the textbook style entry on the newer nSpires is a better interface than RPN for a lot of math - it isn't hard to get very fast with the nSpire menus and the display is pretty much as close to actual math notation as you can get. But RPN feels better for engineering tasks to me.
- wtallis 12y agoHow does the "textbook style" entry on the nSpire compare to the equation writers on HP's graphing calculators? I've never found the equation writer to be quite as efficient for input as RPN.
- yzzxy 12y agoI'm not an RPN expert, but I think the nSpire is holistically better between "good enough" speed and readability. I use Lisp so it's not like I hate alternative notation, I just think classic math notation makes more sense for math.
- underpants 12y agoOnly problem with the nSpire is its a usability disaster. Great for education but as a productive device its horrible. I tried using one (nSpire CAS) for a bit but I felt like I had to do battle with it, not use it.
- wtallis 12y agoThe HPs display symbolic expressions as pretty-printed standard math notation even when the input method is RPN. That's why I'm wondering if the nSpire has any improvement to offer, since HP already has the combination of efficient input and good readability.
