HP calculators are built to be used by professionals. They are built to a standard of quality you seldom see anymore. Unlike calculators from other manufacturers, people who use HP calculators tend to use them for a VERY long time! I have had my HP48g for 8 years now and it still measures up to the competition. YES RPN entry is different BUT it is FAR MORE efficient to use in lengthy or repetitve computations. Unlike Casio,Sharp, and TI, there is a tremendous amount of professional grade software for scientist and engineers widely available. There are games too. The HP48g is solid and it has an IR port as well as a serial port for connection to a computer or other device. This calculator is a powerhouse! If you are a science or engineering major and you want to be serious about your trade then this has to be a device you own!

If you're looking at these reviews because you're considering one, then just get it. I bought my 48G about 16 years ago, and it shows no signs of slowing down. It's literally in the same condition it was in on the day I bought it, and I use the thing just about every day. It spent 8 years being lugged around in a backpack while I was in school, and now it sits on my desk at work.

Some of my favorite features include a huge equation library (find your equation in the list by name, plug in the values, and get the answer you're looking for), statistical charting capabilities, and uploadable programs (For example, I have a graphical Periodic Table on mine).

The manuals are pretty thorough (one user manual, one programming manual), and each one is about the size of a full-length novel.

Chances are, if you're considering this, then you're already familiar with RPN calculators (or at least familiar with stack-based operations on some level). But if you're not, it's okay. It's easy to learn and more efficient. You can also use it normally (infix style) by placing everything in single quotes, like this:

'7+3*5'

And with one button press, it will evaluate the expression for you, heeding all rules of precedence. While I don't recommend using this as a crutch, it can at least ease the transition from a standard infix calc. :-)

=== Update 12/09/2014 ===

The cliche states that the only constant is change, but that's not really true. There are two constants. Change, and my 48G calculator. After leaving the company that I was previously working for, the calculator came home with me and didn't see much use for a while. It was probably a good couple of years.

This isn't so much a review on the power or performance of the 48G as it is the quality, fit/finish and bang for the buck. I can't think of a single electronic device that has been more valuable to me in my engineering career. My 48G was a highschool graduation gift in 1992 and the same calculator is sitting on my desk as I type this almost 20 years later. It still gets used daily and althought it shows a few dents in the metal (!) case it still performs flawlessly. I can't say how many times I've dropped it or spilled something across it in the past but still none of the buttons stick and the screen looks perfect. I wish I could say the same for my 2 year old HP laptop.

Oh, sure, your class will undoubtedly be full of weenies with fancy-looking competitor calculators. They'll be using them to compute french-fry totals at their burger joints after they graduate - if they can figure out how to work them. The HP48G is the serious calculator for serious students and science/engineering professionals. Settle for nothing less than the best!
In a more serious vein, one nice thing you'll find about the HP calculators is that they have tons of third-party software written for them (including some great games!) The 48G is the latest in a line of calculators that's been around for years and years, which is how long it takes to get a good software base established. The competing calculators have no such user community. If you get the HP, you'll be able to rely on a community of people around the world to help you get the most out of your calculator, which is in many ways a pocket computer. Get the HP48G - you won't regret it!

I bought a HP48S in 1993. Even though I was an extremely poor Engineering student at the time, I found it to be money well-spent. The equation solving capabilities of the HP proved to be essential in getting me through tough engineering exams. I liked the 48S so much that I recently bought the HP48GX, and it has proven to be even better than the 48S in many ways. I would recommend this calculator over any other brand on the market to an Engineering student or graduate.

I bought mine about 10 years ago, and I still have it and use it extensively. It has seen use all through pursuing my undergraduate degree and my Ph.D., and in my current work. I have used it for calculating things related to computer graphics, statistics, data compression, and a host of other areas. It has always been up to the task. It is loaded with useful functions and does a lot. Sure, it's not as fast as a more modern one, but it's more than adequate.
