Digital camera reviews of HP 50g Graphing Calculator
Digital camera Review: Great Calculator
Summary: 5 Stars
This is a great calculator, I've had it for about a month now.
It does have a bit of a learning curve.
I had to spend about 2 hours reading the online guide in order to learn how to use the different graphs, as well as how to work with the new menus, use RPN, and other things like solving simultaneous equations.
One thing I really like is that this calculator (unlike the TI 89) has a equation writer. If you have a large and complex equation you are able to input it in without using alot of parentheses, (()(())). You can also edit the equations inside of the equation writer. With this you have alot less mistakes and if you do make a mistake it's usually obvious that the equation doesn't look just like it should.

Summary: 4 Stars
I've been an HP user for 10 years when I purchased my HP48G for high school calculus. I still have the 48G but gave it to my wife for her MBA statistics class. I decided this was a perfect excuse to spring for a new HP. I've had the HP50G for 2 weeks and I am nearly as satisfied as with my old 48G. I am not a fan of the new color scheme, which looks similar to something TI would use, and I am especially irked by the choice of colors for the keys. I was much happier with the color scheme used for the 48G.
NOTE TO HP: Yellow and white look very nearly the same in most light, this makes it easy to get confused when looking at keys like [1/X Y] where Y is an ALPHA character in yellow and 1/X is the function in white.
The plastic feels somewhat cheap compared to the 48G series. Functionally, however, the calculator is far superior in terms of speed, the ability to expand memory cheaply using standard SD cards, and the ability to connect the calculator to a PC using a USB cable. However, I have all sorts of problems using HP's software and hope to find a superior replacement soon.
Overall I am glad I upgraded. If you think about it, 10 years ago the HP48GX was about $250 whereas today's HP50G is ~$135. If you consider 10 years of inflation, $250 in 1996 would be $300 today making the new HP50G a huge bargin.
By the way, I am wondering how long till BW calculators use BW high resolution screens similar to those used by PDA a few years ago. Its seems strange to have a ~160x130 resolution display in the age of 640x480 color screens. I don't want a color screen but 320x240 resolution would be nice.
Digital camera Review: Great Calculator Overall
Summary: 5 Stars
This is a pretty powerful calculator that's in the same league as the TI-89. And if you prefer RPN, like I do, then you'll have to go for this one. The build of the calculator is much improved from the HP 49g+ and the feel of the keyboard is similar to that of the HP 48g, although the keys are harder to press and the legends are painted on instead of double shot molded. The calculator does feel sturdy but the plastic makes it feel cheap. The symbolic integration and differentiation doesn't always work well and some nasty integrals will give nasty results. The TI-89's table lookup might work better for some integrals but I'm sure this calculator can integrate some integrals that the TI can't handle. However the calculator is much faster then the older 48's and the CAS is much improved in terms of usability. 3D graphing is so smooth and fast... although I doubt I'll be doing anything heavy on a small calculator when computers are prevelant. This is not a perfect product, but neither is the TI-89 or the HP-48G. Highly recommended for any scientist, especially the chemists out there who hate math, like I do.Digital camera Review: Great Calculator and great service from Amazon

Digital camera Review: Great Calculator, Horrible Documentation
Summary: 4 Stars
Pros: RPN, nice keyboard, powerful
Cons: Terrible manual, flaky connectivity software
Bottom line: Best calculator out there for engineers (but be warned it is NOT allowed for either the FE or PE exams). More support from HP would be welcomed, as the documentation needs a complete re-write, and the pc link software needs updating. More apps would also be nice, but creating your own is not too difficult once you get the information required to create them.
