Since 1988. I had to do some seaching to get a replacement to one I spilled coffee on. I have one for work and one for home. I've had others, like a HP and a TI-89. This Casio is hard to beat. |

TI-83 Plus
Been using it in; Chemistry, Organic Chemistry, Physics, and every math course up to Pre-Calc and soon to be Calc 1 |

HP-49GX when I am not using Matlab.
And I can choke a PC with Matlab and have to move to a much larger computer a lot. |

TI83+ from ~2002
ETA: I use wolfram alpha whenever I have access to a computer. Does it make me a nerd that within an hour of WolframAlpha Pro being released, I had a subscription? |

Also, the TI-89 was pretty much the weapon of choice for most of us in the engineering school I just came from. I still keep my 89 with me everyday in my briefcase, but now I just use it for simple stuff. Its still nice to be able to go back so many operations and see what I did, which is why I use it and not a simple 4-function. |

I use a HP20s for my daily use (estimating and managing construction projects). When surveying I run the Hp48 with the "cogo" card. I also have a recon with the survey pro app and it works good except I can figure out how to run vertical curves on it. I like using the 48 so i havent spent the time to figure the recon out. It is much more user friendly because you dont have to know squat about surveying, only what buttons to push..
I just realized this was my first post.... How have I been a member for over a year but not posted a dang thing? lol |

HP15c since '83 or '84, and an HP28S I got in '91. Works great with stack logic programs.

TI89, not Titanium.
I actually have a TI89 Titanium too, but the regular one actually clocks faster for some reason. Solve the same problem in both calculators starting at the same time, and the Titanium model takes twice as long... ...on the other hand, the Titanium has more flash memory, so it's a tradeoff. |

Without the solve, matrix math capabilities, and ability to crunch out double/triple/quadruple integrals, good luck taking a test in 55 minutes. Same thing in the ensuing engineering classes; exams would have been impossible without increased computational power. |

TI-89 for a majority of my work.
TI-36 for all the classes where I can use only that in the tests. Mathematica and Wolfram|Alpha for any real heavy lifting, or if I want to work without my calculator. |

I use a TI-36X Pro for electrical engineering work. While I was in college, I used a TI-89 Titanium and a Casio FX-115 MS. I used the Casio FX-115 MS on the Fundamentals of Engineering exam.
I recently did a video review of the TI-36X Pro. Its a newer calculator with a lot of great features for the FE and PE exam. http://www.youtube.com/watch?v=gU6bKaIDKjA |

TI-68, the pinnacle of TI calculator development IMHO. Got me all the way through my MSEE back in the old days.
If anyone has one collecting dust give me a shout. If mine ever dies I'm f%*ked. |

If so, this is good news  |

My TI-89 just went tits up.
 I'm suspecting the backup battery, since as far as I can recall it's the original and I've had it 12+ years.

I ordered a TI-36X after hearing all you guys recommending them. I've been using my TI-89 since college but I really have no use for graphing since then and I would like something smaller to carry when I have to leave my office

Not once in calc III or differential equations or linear algebra did I use a calculator. We weren't allowed to, first, and they wouldn't have helped even if we could. My tests were designed to be done without a calculator. |

My TI-89 lives again! It was the backup battery, as I suspected.
ETA: I am thinking of acquiring an SR-50 to use at work. I'd love to have a retro red LED calculator like my first one. |

bump, out of boredom and lack of desire to study.
I used to use my old, trusty TI-85 every day, but since I was approved to sit my PE exam, I'm now crash-learning the functionality of a TI-36X Pro, since it's approved for the exam...
