Digital camera reviews of HP 50g Graphing Calculator
Digital camera Review: A Great Calculator
Summary: 5 Stars
I switched to the HP 50g from a TI89, and I am pleased so far with how it works. The interface is much different from TI's, so I had to consult the manual to figure out how to use some of the more advanced features. Although there is a bit of a learning curve, getting used to the calculator hasn't taken too much time.
There is one practical consideration that I never thought of. The calculator comes with a leather (or leather-like) case rather than a hard plastic cover. It looks very nice and protects the calculator from scratches, but it allows buttons to be pressed when the calculator is inside. I'll often take it out of my backpack to find it on with a bunch of gibberish on the screen. It only takes a second to clear, but it does drain the battery. If you don't throw it in a bag with a bunch of heavy textbooks, that shouldn't be a problem.
Digital camera Review: A Very Nice Machine
Summary: 5 Stars
I have had the HP50g for one month now and it is very nice to have a machine that doesn't have sticky, clicky buttons. Its all black casing also looks very exquisite and having the Equation Library back again (I had a 48gx for several years) is a good thing. I was going to sell my 49g+ but have kept it as a backup for programmes and data since they communicate so easily via infrared or SD card. I got a 1Gbyte SD card for the 50g so it is a real mean machine now. I think this puts HP back in the hunt as far as serious calc buffs are concerned. They were wobbling a bit there.Digital camera Review: A good replacement for my expired HP48GX
Summary: 5 Stars
I just recieved my new HP50G less than 1 day after ordering it! Wow Amazon/UPS, that was really fast for delivery across the US/Canada border! I'm really impressed with the service.
Having explored the functions for a couple of hours I have found that this calculator appears to be a great replacement for my old and beloved HP48GX. The keyboard has hard keys and nice 'click' unlike the much maligned HP49 keyboard. The smaller re-located entry key will take getting used to. Processing so far seems faster than older models.
I found many of the functions just as I had them on the HP48GX (equation library, matrix editor, constants library).
One that so far looks a little more clumsy is the units editor and converter. The units editor is now a pull down menu instead of using the multi-function keys at the top of the keyboard. So far I've found this a little slower to use.
I'm also missing the 'PLOT' function which has disappeared from the keyboard. I was also missing the 'SWAP' function but have since discovered that it's still there using the right arrow key, but is not labelled.
These little differences aside I'm really happy with the product.
Digital camera Review: A heck of a calc
Summary: 5 Stars
Very nice Calculator, tried it from a friend before buying it, so i knew I'd like it. Came on time and as described.Digital camera Review: After proper setup it works perfect. Its the best.
Summary: 5 Stars
The HP 50g is the best Graphics calculator out there. Especially if you understand and use RPN. You must have a great deal of experience with Graphics calculators to truly appreciate it's excellent qualities. Because it does not come with a complete beginners guide, beginners must be prepared to spend several hours to learn everything about the device. I do not recommend that beginners in mathematics attempt this without accessing third party training manuals for this calculator. It is a fine product. BTW if you want an excellent, well designed number cruncher, get the new HP 35. It's simply excellent!
UPDATE:
I've read a lot of complaints about how this device is not as good as my old HPxxxx.... There is a problem with calculators today.... they need to do more.... but there is no real estate on the keypad..... I use SciLab on Linux and MATLab on Windows almost all the time. Most colleges encourage this. Graphic Calculators are a thing of the past.
