Rated 5 out of 5Â by Sccaj7 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!

Rated 1 out of 5Â by Schlittenfahrt 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.

Rated 5 out of 5Â by dwpvdk 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.
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.
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."
"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 5Â by MOSwas71331 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.

Rated 5 out of 5Â by dingebre Excellent, my new favorite
I've owned and loved an HP35, 45, 67, 41CV, 41CX, 48GX, and now a 50G. I had a 49G, didn't love it so much... I still own and use the 41CX and 48GX. I decided to buy the 50 to develop some programs for work, and I was attracted to the larger display and connectivity. I love it. It feels good in my hand, the keys have a good snap to them, and the color is much better than the 49. I can appreciate the location for the enter key, but it's taken some getting used to. All in all, a great calculator.

Rated 5 out of 5Â by RPNut A real tool for engineers and other professionals
The 50G is much more than a calculator. I got mine in sophomore year of college when I took Circuits I and found out that my TI-84 couldn't handle matrices with complex numbers. The professor teaching that class was a die hard HP user. I didn't feel like spending another $100 or more on another calculator (the only other option was the TI-89 which I had used and didn't like) and he had convinced me that HP was the way to go. From the second I pressed the first key, I knew that this was the beginning of a different but great journey.
I appreciate the wealth of functions that are available on this machine, as well as the programming capabilities. It deals with complex numbers without a problem. I also use the equation solver all the time. The ability to solve an equation symbolically (using only variables, no numbers) is great too. Being able to take partial derivatives is nice (the math department knew that the TI-89 could take partials, and thus, was not allowed on exams, but had no idea what an HP 50G was). I could go on and on, but you get the idea.
This part takes a little getting used to. If you were to plot the sine of x, as in, y = sin (x), you may not get what you would expect to see on a TI-84, but when you play around with the scaling and things, it actually makes more sense.
3D GRAPHING! WOW! Can anyone else's calculator do that (this was another math department lack of knowledge, 3D graphing was great for the chapter on surfaces in calc 3)?
I can't count how many times I've used this baby to perform mesh analysis in a circuits problem (and do it faster than anyone else). I was also able to do Laplace Transforms faster. This calculator has also proved very useful in Electromagnetic Field Theory; finding curl and divergence of a 3D vector field is a snap! I once tried to transfer a program to my friend's 50G but forgot the cable. I then remembered that IT HAS INFRARED DATA TRANSFER! I can't imagine ever running out of memory, but having that SD card slot is great too. Being able to use units in a calculation is a very useful feature.
Has RPN (and Algebraic too, if you don't want to learn RPN)
Feels like a real tool rather than a cheap calculator
Comes with a faux leather case, not a cheap hard cover
Has an extremely large library of functions covering every discipline (and a constants library too!)
Has IR data transfer (seldom found in other calculators)
Can be programmed in C
Is comparable in price to similar models (but is WAY better)
The numeric equation solver cannot deal with complex numbers
The ENTER key is not double sized like classic HPs (but who really cares? If THAT'S your deal breaker, you've got problems)
The case does not have a belt loop (I stitched my own on)
All in all, I consider this to be the best purchase I have made in my college career. I think that should say enough. If you're on the fence, give HP calculators a try, the only regret you'll have is that you didn't try them sooner!
