I have been on holidays like many of you, and with two young kids, I had very little time to spare for my hobbies (currently audio and calculators). So it is with a smile that I am coming back to work.
I have been using the HP39GII for some time. The programming model is good! It will covert many more people to our loved brand than RPL. If you think about it, RPL is elegant, a direct extension of what RPN was, and powerful; but at the same time, it is even less readable than RPN (to my taste - YMMV), and nothing compared with BASIC or any structured language, including C. (libraries management is what always made C unbearable for anything made for pleasure and not for money)
This calculator is the ideal companion for a kid learning maths. It can help him to see what if, changing equations, immediately seeing the graph (in a much friendlier way than the 50g), and it is easily programmable. It does not have the steep learning curve of RPL.
I look forward this term to teach my elder kid (9 years old) some math concepts with the HP39GII. It will be a much easier job than with the HP50g.
HP will release the HP50g replacement most likely next year. I hope it is built on the same concept - of course, keeping the RPL programming model AND adding the programming language introduced by the HPgII at the same time. Let's agree that the HPGCC, while being an incredible tool to do whatever you want for your calculator, it's for us nerds, and not for the laymen engineers that are the normal customers for this calculators. The current HP50g has the mathematicians' and physicists' side covered with its current feature set. Let's add the market of the engineers that just want to use it as a tool to solve their day-to-day problems with very limited time expenditure. The HPGII has opened the way - let's hope HP follows suit!
All distributors seem to be getting rid of their blue HP50g - take the opportunity and complete your collection!
