Buyer's feedback: - * Not for general use ...
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.

Buyer's feedback: - * Not a step down from the HP-48G ...
It was inevetable my 48GX would croak someday. Someday turned out to be last week. I've been running the SMI BCE COGO land surveying software on it since the mid 90's. Although it hasn't gotten a lot of use since affordable COGO/CAD software for PCs became available, it was handy enought as a backup for doing quick calcs. replacing it was a necessity. The 50g is running D'Zign's Basic Cogo+. Because of its more rounded contours it feels more comfortable than the 48 when cradled in a two-hand hold, and has a pleasing heft to it. The keys have a positive stroke to them when doing two-thumb data entry, and the display is easy to read under flourecent lighting. Too bad it won't talk to the little thermal printer I used with the 48.

Buyer's feedback: - HP quality is back!
Having owned and used a variety of HP calculators over the years, I've seen the build quality drop steadily. For example, I still have, and use, a HP-12C financial calculator that I bought in the early 80's. It's far better made than the current versions, even with the feet and silkscreened print worn off the back, and retains a like-new feel. HP's recent calculators, whatever their level of functions and features, have felt pretty cheesy. With the 50g, HP has made a big step back to quality. It feels good, though it doesn't rise to the quality level that originally made HP famous. But with the features, flexibility, and speed it provides, is really the best scientific calculator available, once you get past the religious arguments of TI vs HP.

If RPN is hanging you up, don't let it. The 50g supports a number of notational approaches. The other principal objection to HP calculators vs. TI reduces to simple familiarity, as TIs are almost universally-used in school settings. If you are a TI user, you will find that switching is trivial. Those who do sometimes report an interesting reaction - feeling betrayed by the schools when they realize just how much better the HP is!

I do agree 100% with other reviewers that the manual is a big, big disappointment. Count mine as another vote for complete, spiral-bound manuals.

Buyer's feedback: - * Powerful Calculator at an affordable price. Big upgrade from my HP 39. ...
This HP50G is by far the best Graphing calculator in the market as of now. It is fast, and capable of doing many things, yet it can be complicated to use for the average student. I'm still learning how to use the thing as I am currently writing this review. If you do not mind putting hours into learning the manual yourself then this product is for you. Some might be scared because of their classes and Instructors only uses TI models, but don't be scared. Once you've mastered how to use it you'll be the one in the classroom with the competitive edge from the rest. For those that are first time buyers for calculators I may have to suggest getting the Casio 9860G model for its easier learning curve. The Casio 9860G is just as good as the TI model and also has a moderately faster Computer Processor.
