HP 48GII Graphic Calculator (F2226A)

I bought this calculator a few months ago. Used to use a 42s, as well as 32 versions. I haven't had any trouble adapting to the new enter-key location, and after spending some time studying this more complicated computing device, I sort of like many of the features. However, the keyboard on mine is unacceptable. As others have commented (both here and on the page for the 49g+), the keys will sometimes miss the keystroke. I find this totally unacceptable, and I, like others lament the decline of quality in HP (at least in the calculator arena). But, I'm hooked on RPN and TI doesn't have it. I plan to try to return my 48gii to HP and see if they have actually fixed the problem (some reviews of the 49+ look hopeful in this regard). If you have a newer model and the keyboard works perfectly (which it should), please post here so we can once again get people buying HP calculators! It will do us all good ;-) *** OK - I called HP support. They were very nice and sent me a new calculator. The calculator had an earlier serial than the one I already had - so I wasn't hopeful, despite what they told me. Sure enough, it acted about the same. HOWEVER: 1) This was a couple of months ago, so it is possible manufacturing has improved in the mean time. 2) I have found a good workaround: Turn on the keystroke beep sound. It's not too loud, does not bother me, and most important, it is very obvious now when it misses a keystroke. I don't have to look at the display - which slows down work. Instead, my senses detect the missing beep without even thinking and I then just hit the key again. I strongly recommend this for anyone with an existing calculator with the problem - and am hopeful based on some recent reviews that HP may finally have fixed the issue on the latest ones being produced...

I must admit that I am loyal to HP calculators! I bought the HP35 in the early 70's when I was a graduate student at Washington University. I currently collect HP calculators.When I bought the HP 48gII about a month ago I encounted the much talked about keyboard problem. I did what comes naturally. I called customer service. A very friendly representative took my name, address, and the model and serial number of the problem calculator. In about 30 seconds I was informed that a problem free calculator would be on the the way in 3 to 5 business days! I was also given a case number so that I could keep tabs on the progress of the shipment of the replacement. Note that I did not ask for a replacement! The company apparently is on top of the problem and know exactly which calculators need replacement. I asked about instructions for returning the problem calculator and was told to wait for further instruction from HP. If I do not hear from HP in 30 days, I may dispose of the problem calculator as I see fit. What else could one hope for?In four business days I received my new HP48gII with three 3AAA cells and two memory cells. The calculator only reguires one memory cell. I immediately checked out the calculator. My problem calculator would ocassionally not respond to the pressing of the up/down and left/right keys. At times others would not respond. With the new calculator I have not experienced any problems.Go on. Stop listening to the foolishness. Get the best calculator out there. Get the HP48gII!

I love the line of RPN calculators from HP. Mine that I had through college finally gave out, so I got this one. Took me a little be to figure out how to put the mode calculator into RPN mode (that's reverse postfix notation - not reverse polish notation!). Once I got that then I was much happier!Anyway, the keyboard layout is worse than the older version, but there better menus and on-screen navigation. The speed of this thing is great! I noticed that there are no expansion slots, but I bet that the memory and functions in this one more than makes up for the lack of slots.Oh, the price is AMAZING! 'course I bought mine in college for over $550, while this one was less than 10% of that. So I'll leave plenty of room for the shortcomings of this model, because it's super cheap.Be careful if you let this calculator get cold (like in your backpack on a cold day) - the keys get really stiff and it's hard to input anything. Also, the flexible circuit under the keys can crack if you push a key and the circuit is too cold. This is the same problem with the older model, but just give it 10 minutes and it will be fine.

I had the old 48G and loved it. Actually I loved everything about it, but had to get a new one when the "on" button gave up after 18 years.So, I looked around some and found this one used for a great price and bought it. It's a good calculator but the buttons are its weakest point by far. They are just not very fluid. Sometimes you can hit a button twice yet nothing happens, rather annoying when you are looking at the numbers when punching them in instead of at the screen since you won't notice the "mistakes" until you are doing your calaculations.Note to HP, go back to the "old" buttons, they were loads better.
