Digital camera reviews of HP 50g Graphing Calculator
Digital camera Review: (Almost) Just like my old 48GX
Summary: 5 Stars
My trusty old 48GX recently started acting up - some keys just didn't work that well any longer. So I decided to start looking around for a replacement. I settled on a 50G. I'm glad I did.
My thoughts:
1. The obvious: Same size as 48GX but with a larger screen.
2. It's a lot lighter than the 48GX. This makes it feel somewhat funny in my hands - being used to the nice solid feel of the old one. It seems to be put together quite well, though.
3. The biggest change on the keypad is that "enter" moved from left-center to right-bottom. I barely notice this as I mostly use the calculator for math, and with RPN you don't really need an "enter" key for that.
4. It's a lot faster than the old one.
5. It has some extra stuff - libraries and so on - but I think these are mostly used by students, so I can't comment on them.
I'm suitably impressed. I think this is a worthy replacement. It's definitely not better than the old one. It feels more like a good copy, with some added features that no one will really use. Almost like a Lexus.
Digital camera Review: 48G Upgraders Take Note
Summary: 4 Stars
I am a long time user of the HP 48G, which I accidentally dropped and broke a month ago. When I got on-line to purchase a new one, I decided to upgrade to the HP 50G. Overall, I am happy with the purchase and I do not regret my decision in the least. I thought it might be good to point out some differences that have caused some adjusting on my part to the calculator. First, the ENTER key has been moved from the upper left side of the calculator to the lower right. This still causes me to pause a second before entering in values. Second, the new ENTER location shifts the arithmetic function keys up one position, which causes me to hit the wrong function from time to time. Third, the calculator is not in RPN by default. You must go in and set this parameter in the MODE setting. For this reason, I recommend that you read at least the first two chapters of the users manual to get the calculator set up in a manner that will be most familiar to you, or to understand the default settings. Speaking of the users manual, the manual did not install from the provided CD onto my computer (I do not know why), and I ended up having to download it from the HP website. When I finally did get the manual, it was primarily written for the 49G instead of the 50G, which made some of the instructions incorrect or impossible. For example, at one point, I was instructed to hit the I/O key, which exists on the 48G and the 49G, but not on the 50G. If you are used to the 48G, and need to hit the ground running, then be aware of these changes.Digital camera Review: 5 Star ReviewThe HP50G is a robust graphing scientific calculator

I have an HP49G+ and now I bought this mainly for the much better keyboard feeling and the serial connectivity option. Due to its black color it reminds more of a TI instead of an HP but this is not a problem. Some comments found on other sites about the display are not true. It is as bright as that of the HP49G+ and has the same functionality but somehow it fits more information. The HP50G formats a 512 MB SD card faster than the HP49G+ and it feels a little heavier due to the 4 AAA batteries (the 49G+ uses only three). The keyboard is SOOOO SOFT and has nothing to do with that of the 49G+ (no noise at all when you press buttons, no missing keystrokes). The soft deluxe case is a plus and the CD has everything you need to get you going. The serial cable is missing and I have to make one myself since HP does not have one yet in the market. In any case, if you are a student or scientist you need one. The menus are better than those found on the titanium TI89, and the HP50G is not as heavy as the TI is. Not to mention that the lettering brings to mind that of the good old HP48GX. We all know that HP has been making calculators for many many years and now they are back with a robust product that is here to stay and can win the competition. Add its price of $124 with free shipping and no tax and then ask yourself: what more do I need? Nothing. Go get one!!Digital camera Review: 5 star calculator with 0 star documentation
Summary: 1 Stars
This is very powerfull, complex calculator, much according to old HP spirit and quality. Unfortunately, manuals are below of ANY acceptable quality standards. There is short (150 pages) User Manual, very poorly written, not even explaining the concept of RPN and stack manipulations. There are some keys that perform stack manipulation (DUP, DROP) but they are not described; I discovered these keys just by accident. It is not clear for me how person new to RPN can start using this calculator if basic concepts are not explained.
Manual is extremely poorly printed. Reading keystrokes sequences needs strong magnifying glass.
More complete User's Guide is abaliable only in electronic form (on attached CD), but Advanced Guide (needed to program) is available only from HP site under HP-49 information. These manual are equally poor as the first one. Printing these manuals is expensive; actually more expensive than the calculator itself. There are 1600 pages to print; Kinko takes 16 cents per page. This would make $256. This means that computer is necessary attachment to the calculator. It this situation, I don't need the calculator: If I have to take calculator AND laptop to a trip, then I can do all calculations I need using laptop.
I have been using HP calculators since HP-41; HP manuals that time were publishing marvels. This what happens with manuals for HP-50 (and actually all manulas for modern HP calculators) is the evidence of fall of this once great company.
