The Best Graphing Calculator on the Market?

aaronbeekay asks: "I'm a sophomore in high school taking an honors chem course. I'm being forced to buy something handheld for a calculator (I've been using Qalculate! and GraphMonkey on my Thinkpad until now). I see people all around me with TIs and think 'there could be something so much better'. The low-res, monochrome display just isn't appealing to me for $100-150, and I'd like for it to last through college. Is there something I can use close to the same price range with better screen, more usable, and more powerful? Which high-tech calculators do you guys use?"

    HP-48GX, hands down for engineers.

    There is just something fundamentally appealing to owning a powerful calculator 90% of the population can't even add two numbers on...

      My wife teaches Fluid Dynamics and she's doing something with that HP-48 every night. Whatever it is, I'm not allowed to touch it. She carries that thing around like it was the crown jewels. When she was pregnant she left her graphing calculator in her office and I had to walk 2 miles in a Chicago blizzard to get it for her.

      A few years ago I was doing the taxes and I reached for it to do some arithmetic and she nearly broke my hand. But that might just be her Eastern European sternness coming through. I got a little too enthusiastic on one of our first dates and almost lost the hand that time, too.

      Dude, didn't anyone teach you--you *never* reach for a woman's HP48 on a first date! It's probably not a good idea to even touch their Ti's.

    I disagree. I paid about $300CAD for my Ti-89 and not only is not allowed on tests neither at the grade 12 level nor first year college

    Maybe it's because you're in Canadia. In the US, the TI-89 is explicitly allowed on tests administered by the college board (but not ACT). It's also the reason I bought it, the TI-92 isn't allowed on any tests.

    mine's already broken after only about 2 years of seldom use.

    How odd, I bought mine when it was first release (1998) and it's still going strong. Maybe it's the Canadian weather that caused yours to fail. Also, you're not supposed to use it while taking a shower.

    "Oh, and you could probably dip it in motor oil, and it would still work"
    Don't know about your HP-48 (which I own too, by the way), but one day the tomcat puked right onto my old HP-32S, which it didn't appreciate at all. I had to disassemble it (try that with the tank-like construction of HPs, took me me 2 hours) in order to clean it and make it work again.

    The best part about RPN is when that smart-ass pre-med in chem lab borrows it, punches in a bunch of numbers, and then asks, "Where's the equals key?"... Priceless

    When I was in high school a lot of students used those "notes" for chemistry tests since we were allowed a calculator. Eventually word got out and when we went into Calc one day, the teacher collected all the calculators for inspection (they were all owned by the school and issued for the year, so they could do this). Everyone who had any text notes about chemistry in them caught hell. Can't remember exactly what happened, but it wasn't pretty, and we were banned from using any graphing calculators in chemistry from that point on.

    Luckily, I'd never stored any notes in my calc, but several of my friends had.

    We were limited to Casio and TI because they knew how to wipe those.
    Heh. In high school I wrote a program for the TI 83+ (what we all used) that had the keystrokes for wiping the memory preprogrammed. I'd run that program before the teacher came to wipe the memory, she'd go through and wipe the memory, but she was really just running my program. Basically it was like if I had, in autoexec.bat back in the day, a basic program run which was

    DO WHILE 1 < 2
          INPUT "C:\>",
    LOOP

    And when I say, "I'd run that program," what I really mean is, "I'd imagine myself running the program, but didn't have the balls to actually do it." I mean, that's cheating.
