Customer ratings and reviews for HP 50g Graphing Calculator

Rated 5 out of 5 by Better than the 49 & 48 This replaces a 49G that just died one day. The case is more solid than the 49 and the key response is better than the 49 and similar to the 48. Also adds some bells and whistles. March 19, 2014
Rated 4 out of 5 by Installation Disk Problems The connection from the usb port to my hp dv7 laptop running Windows 8.1 fails from the installation disk provided. I now have to spend time 1) trying to figure out how to get tech support for an hp calculator, and 2) how to get past the installation failure. I am recommending the product in the event that I am the only one having this problem. December 6, 2013
Rated 5 out of 5 by Love it I've used the 11C & the 48GX for years. I will always stay with HP for calculators. I've had the new 50G for about a week now. Still getting used to the new location of the ENTER button, but otherwise, I love it! July 11, 2013
Rated 1 out of 5 by NOT the HP calculator of old!! It's a piece of junk!! The documentation is poorly written in that it's hard to follow. The calculator doesn't want to interface with Windows 7. It's now sitting in a drawer; I bought a TI Voyage 200 and am using it instead. April 11, 2013
Rated 5 out of 5 by Why aren't there more sales resources for the 50g? This is the best calculator (or handheld computer) on the market, and yet the only way I obtained it was that I found out about it through my father, a surveyor who uses his trusty 48gx as a data collector. He hooks it up to his instrument and does surveying with it all day. He also has had twelve 41c models over the years, one or two 11c models, and one 38sx2. He purchased 15cLE models for me and him. When I was smaller the 38 was around the house and I used it for math class. I learned to use RPN very young, and I had to use algebraic calculators at school, so I consider myself unbiased. RPN I consider RPN to be much easier than algebraic to use. It may be a little more difficult to understand the stack (my father taught me when I was six using index cards with numbers written on them arranged in a vertical line), but the knowledge pays off considering the time necessary to do large expressions and equations. Whenever I forgot my calculator to school, I hated typing the parentheses and making mistakes. I believe that an RPN calculator is an extension of your mind, because it works the exact same way. Features of the HP50g 3d graphing, as I am in highschool it will probably be for the most part useless, but I know it will be very useful in college. However, it is very fun to mess with and it is the only calculator that has this feature that I know of. The filesystem is great. I have made RPL programs that handle data written in files such as a database manager and creator and a school agenda that tells you what today's homework is. Functionality Since I am in geometry, I have to have exact answers for radical and rational equations. I use exact mode all the time and it is better than approximating radicals and rational equations with a TI-x. It is very hard to make mistakes since you are actually thinking through each step of the problem, expression...etc. and this gets me better grades and faster test times than most of my classmates. All thanks to the HP. And when I want the approximation, you don't even have to switch modes. ->num is a great tool as well. My classmates always wonder why I am so fast at calculation on a calculator, and when they come check it out, it is the greatest calculator in their opinion, better than all the TI merchandise. If there was better advertising of this product, there would be insane demand as if there was not already. Here is a sample dialog of a conversation with a TI fanboy: "Yeah, well you can play games on this calulator." "You can make games on this calculator." I say. "Ok... Best calculator ever." OR "Yeah, well you can graph on this calculator." "You can 3D graph on this calculator." I say. Some of the more practical members of our society ask me what the purpose of all this functionality and connectivity of this calculator is. This only requires a quick ~3 minute demonstration of its 771 functions. I feel indebted to HP, so I buy all of your products. I have a hp computer and am about to buy another. Thanks guys.

Rated 3 out of 5 by Calculator is far from intuitive -- too far The 50g comes with a short instructional guide which it estimates you can complete in about an hour. I couldn't complete the first ten pages of the guide in my first hour of working through it. Having owned five HP calculators since I bought my first in the early 1970s, I was already familiar with RPN. That didn't help! The 50g has over 100 flags affecting its operations, and it's hard to anticipate how those flag settings occur and how they'll affect calculator operation. I tutor college algebra and intro calculus at a community college, and I find my HP 41C way more useful than my 50g for helping students solve problems. The 50g has an 800+ page manual you can download -- which I have done. The manual shows the 50g has many features built in (why I gave it 5 stars), but mastering them will take more than a few days of work. That reward doesn't justify the effort. March 10, 2013
