In Calculator Arms Race, Casio Fires Back: Color Touchscreen ClassPad

KermMartian writes "In what seems to be an accelerating arms race for graphing calculator supremacy between Texas Instruments and Casio, the underdog Casio has fired a return salvo to the recently-announced TI-84 Plus C Silver Edition. The new ClassPad fx-CP400 has a massive color touchscreen and a Matlab-esque CAS. Though not accepted on the SAT/ACT, will such a powerful device gain a strong following among engineers and professionals?"

      Reliving history? How so?

      First of all, you have to keep in mind the intended use. A calculator is a tool for doing math. Period. How much space do you need for that? I added some very cool stuff to my old HP-48, which only had 32K. For math stuff, you simply do not need a lot of extra space. A few megs seems like overkill.

      A calculator is NOT a PDA. A PDA has always been intended to be more of a general-purpose device. While phone numbers and appointments were the strong point of a PDA, word processors, spreadsheets, and games have always been in the picture. Calculators, on the other hand, anre not designed for games and word processing. If that is the sort of stuff that you want, just buy a tablet instead and throw a $5 calculator app on there.

      You always have to keep in mind the intended usage. Even the cheapest graphic calculator has more memory than my digital wristwatch (and I am primitive enough to still think that digital wristwatches are a good idea). I would argue that my watch has enough memory to do its job, and really does not need more -- just like calculators.

      OK. Let me modify that. Memory for the sake of memory is not really a necessary. If you stuff a calculator full of memory and put more advanced math stuff in there (like a mini-matlab or mini-mathemtica), then that is probably a good idea, but if you are doing a lot of symbolic stuff, you probably need a rea; alphabetic keyboard -- which means computer or tablet anyways.

    For the past year or two, I really haven't seen anyone use a calculator that wasn't on their phone. Most people don't even wear watches anymore, 'cause their phone shows the time. Until now, I had no clue that any companies were still doing serious business of calculators. I think they've seen their time, and fewer will be sold. I'm sure watch makers see their time is coming too. They may sell, but I can't think that it'll be a large market, or even half the market it was 5-10 years ago.

    Aside from non-technical advantages (e.g., being allowed to use particular ones in exames), in general for graphing (and just plain scientific, engineering, or financial) calculators, a big plus is a physical keyboard optimized for the particular use. That's actually a weak point of this new Casio device (which seems to have very few keys other than the numeric keys), so I doubt it will catch on, but specialty calculators in general still have advantages, though general purpose devices will often be good enough for most users.

  40. Cute math paradox by Zinho · · Score: 1

    . . . The other is identify useless data. For instance, "Three customers give the $10 they each owe to their waiter. His boss hands $5 back to the waiter, saying it's on the house because they're regulars. The waiter pockets $2 as a tip, and gives $1 back to each customer. How much did each customer pay? Isn't it weird that 3 * $9 + $2 != 3 * $10?

    This may be the first time I've been presented with that problem. It first struck me as a paradox like the one where I count my fingers forward from 1 on one hand and backward from 10 on the other, then add 5+6=11 to say I have eleven fingers. After scribbling a bit here's what I've come up with:

    Net change of money:
    Owner: +$25
    Waiter: +$2
    Cust1: -$9
    Cust2: -$9
    Cust3: -$9

    This all balances out, the sum of those values is zero (+27-27=0). Adding the +$2 to the -$27 to get $29 is wrong, and not (in my opinion) a problem with useless data but instead with sloppy equation prep. The other distraction is comparing it to the $30 they all paid originally; a better question seems to be "Where did the $5 change go?" The answer to that is obvious, $2 went to the Waiter, $3 to the customers. The paradox all seems to come from the confusion of money paid vs money refunded and not keeping signs straight.

    Sorry if I'm coming across as a wet blanket here! Incidentally, my wife hates it when I get all mathy on stuff like this; she'll have the right answers to household budget questions by the time I've finished figuring out which columns to put things in. I just like clearly understanding why my math works out right instead of going on my gut; it keeps me from asking questions like the one posed in your paradox =)

      Not sure I agree with this. I went to a course on quantitative risk analysis for engineers recently, and every participant there had a graphing calculator, and used them frequently. I actually bought one recently (TI Inspire TX CAS or something similar) because sometimes it's helpful to have a purpose-built instrument which can graphically show things to clients etc.
