HP Prime Graphing Calculator

Slightly disappointing
09/23/2014, posted by Dr.
I had an HP48G scientific calculator for over twenty years and used it with great success in dealing with university and researchlevel mathematical problems. The HP Prime is a beautiful machine, but appears to be aimed primarily at gadgetorientated 17 and 18 yearolds. The hope that the HP Prime would be able to do things that my HP48G could not for reasons of, for instance, memory limitations did not come true. As a practical and handy tool for a mathematical scientist the HP Prime does not live up to the promise of its impressive memory and high calculating speed.

HP Prime, a good product flawed.

I have several reasons for wanting to buy an HP calculator, and I've had many over the years (I really miss my 48SX.) At 50, I am considering going back to college / uni and studying maths for pleasure and electronics. I currently have an HP 35 (new version) but fancied a new toy/tool/gadget. Two things really irritated me: 1. No paper manual to read, not even if I wanted to PAY for one. 2. The light blue 2nd function key settings are hard to read even under good lighting conditions. I have other gripes, but those are the main two I reckon that I could design the perfect calculator/computer for you.

Nice Calculator

This is a nice calc. Just got it. Found this problems:  if you're in RPN in the home.settings, then I cannot enter any function to any graph ! I have to revert back to textbook before any graph !!!  The blue color on the keys is nearly invisible. It is not usable if you have not a strong light and a good sight.
