Summary: good but not great
Comment: So I do math all the time and I need a good calculator. I have a few that I use but I was looking for the ultimate. Its unfortunately not the HP 50g. Although it is an absolutely amazing tool it is absolutely amazingly hard to use. The instructions don"t help, it beeps at you when you enter things wrong. On the good side RPN is awesome as always. The equation library and constant library are awesome. The calculator has keys that provide a good tactile feel and click. The graph application is weak, or at least I cant figure out how to use it after reading the instructions. Get a Casio class pad 330 instead.

Summary: I loved this calculator
Comment: I like this calculator as the functions are easy to understand. Unfortunately, this does not have home screen with ikons as in Texas Instruments Ti89 Titanium. I have both these calculators and I will say both of these are equally good.

Comment: Oh how I wish I hadn't spilled soda on my 32sii... I purchased the HP50 as an upgrade/ replacement for the 32. I've owned several HP RPN calculators over the decades but I can't get over how awkward this unit is to use. The manual is terrible at explaining the functions, it seems to be random on when they explain step by step versus vague descriptions of the features. I still haven't figured out how to do a conversion between liters and gallons rather than having to remember 3.79.
This thing will be a brick for all but the most devoted users.
I now know why people are willing to pay several hundred dollars for a used 32sii.
