    • For introductory courses I suggest going with something like the TI-84
One should be aware that the TI-89 can do everything. That's its problem. Since it can do everything, you have to do more button pushing to instruct it to do what you want it to do. On too many occasions finding the correct sequence of buttons to push isn't evident. Technically, this "flaw" is referred to as "cryptic" input. You can read all about it on Wikipedia. So, if your future has you taking only an introductory level physics course, I suggest going with something like the TI-84. I got the TI-89 because I'm a professional and felt I was honor bound to master it. I also have a TI-86 and feel it was a mistake of TI to discontinue it. There is one circumstance of a difficult transcendental equation that I had solved analytically by hand. I wanted to see how the TI-89 did with it, since it supposedly has all the algebra in the world built in. It only succeeded in transforming the appearance of the equation, but didn't solve it. By the way, my analytic solution has passed countless numerical tests. ... show more

    • Around Since 2004, it's Still a Good Workhorse
Bought three years ago in 2016 to retire a TI-85 that was 21 years old. Still going strong but the means and data link technology to connect it to a PC was designed in the era of Windows 3.1 and just beginning to transition to Windows 95. The TI-89 has been everything I expected and more in supplanting the TI-85. For some beginning and younger students it might be a bit of overkill. Consider the features and functions this one has compared to one of the several TI-84 still in production and make a cost effectiveness decision. The more complex and feature laden, the bigger the learning curve. Also be aware that a TI-89 of any type cannot be used on an ACT exam (as of my writing this in 2019). HS students preparing to take the ACT will need a calculator that is allowed and it should be one they're sufficiently familiar with to use on the exam without fumbling around with it. Shouldn't deter getting this calculator, but they'll need a different one and should practice with it for the ACT. A calculator is still handy for use out of the office when hauling a laptop around isn't very convenient. Even then, my laptop is often tied up with other tasks using a browser and MS Office when I need to use the calculator. Pulling out the TI-89 Titanium (or an HP 50g I also have) is much easier than fussing around with Excel. The case is quite robust and after three years the keyboard is very responsive without sticking keys, key bounce, or non-responsive keys. Keycap labels are still as legible as when it was new. Take care of it without sliming it with food, or spilling beverages on it and it will last for many years. I'm giving it four stars overall as the technology under the hood with a B/W screen is 15 years old now. Its gets 5 stars for sturdiness, value and durability as those don't consider the technology inside. Those needing high end speed and sophistication for advanced applications should look at the TI-Nspire and HP Prime models. (The HP equivalent to this one is the 50g.) One drawback for the color backlit screens on the Nspire and Prime models is use in bright sun. Reflective B/W LCD panels are easier to see and read in direct sunlight. ... show more

    • One of the most powerful algebraic graphing calculators, with a superb command/edit line.
I bought the TI-89 Titanium to be compatible with a fellow engineer--it is great to be able to share code and math solutions for the same model of calculator. This is a switch for me, since I have always been a Hewlett-Packard fan. I have at least one of almost every model of HP graphing calculator, and many other models, going all the way back to 1972 and the HP 35. It never occurred to me that the TI-89 series could actually be competitive with HP. Well, it is! This calculator has some very nice features, and a few features that the similarly capable HP 49G does not. I'll leave it to the buyer to explore the manuals and figure some of that out for themselves. But I will definitely note that the Home screen edit/command line has superior behavior in several ways to the HP 49G. One of those is the retention of the last problem, equation or expression entered by the user. That means you can simply solve the first problem, then move the cursor around in the problem, replace a variable, change a sign, or make any other edit needed to evaluate the problem in different ways, without having to copy the equation/expression from the history (as you would have to do with the HP 49G). The HP 49G has more memory than the TI-89 Titanium (mine is a HW4 edition), and a more feature-rich file system (more like a PC). TI partially compensates for simpler filesystem by having apps show only files appropriate for the app you are using at the time, which helps avoid visual clutter. The TI-89 Titanium has a lot of useful, very high quality apps, preinstalled. Both models have a CAS and about 800 scientific functions, constants, and unit conversions but, while unit conversions are faster and easier on the HP 49G, unit math is better on the TI 89 Titanium if what you expect the calculator to do is simplify units to the most practical SI or SAE unit. As an example, if you multiply 200,000_Pa by 1_l, the simple answer is 200e3_Pa*l, but the most practical SI unit resulting from that product is the Joule. The TI-89 Titanium correctly substitutes units and answers with 200e3_J, while the HP 49G (and later RPL graphers) renders the easiest, but least helpful, answer of 200_kPa*l--the correct answer, but left in inconvenient units. (The 49G does have the advantage of having metric/engineering power-of-3 prefixes, such as k, M, G, m, n, etc.) In a way, the TI-89 series is as much a personal digital assistant (PDA) as it is a graphing calculator. This is the result of having numerous useful record-keeping applications, a clock/calendar, event scheduler, task manager, personal contact database, etc. The Titanium also comes preloaded with EE*Pro, a professional-quality problem solver app aimed primarily at electrical engineering professionals. The closest preloaded application HP shipped with a later model of the 49G series, the HP 50g, was a library of powerful equations copied from the HP 48G series, and an interactive Periodic Table of the Elements for chemistry. Don't get me wrong, those are very useful, and the Periodic Table app is better than ones I've seen for TI. But, the TI-89 series was marketed to students and professionals alike as more than just a graphing calculator with a CAS. It is a PDA. In 2020, that seems a silly point to make, given smartphones of today. But in 1999, when both the HP 49G and the TI-89 series were made, the TI appears to have been a better fit for students and, depending on the disciplines, maybe better for engineers. In most respects, the I prefer the HP, but some features of the TI are eye-opening ideas that explain to me why TI is still making graphing calculators for the US market today, while HP has fallen out of the business in the US, even after the release of the formidable and capable HP Prime (which is, in my opinion, superior to the TI-Nspire CX series). TI showed a better design balance with the 89 series, making the flagship graphing calculators fit either the student or the professional technical user, and most apps for the TI-89 series are of very high quality. One more point I will make, is that both are programmable; the TI-89 Titanium is natively programmable in TI BASIC, while the HP 49G is natively programmable in HP Basic and in UserRPL. HP Basic (not BASIC) is limited compared with TI's M68000 BASIC, but HP RPL is more powerful, more elegant, faster for most programs, and more efficient than TI's BASIC. However, TI BASIC is pretty intuitive, while RPL is considerably harder to learn if the user is not already familiar with Reverse Polish Notation and the HP stack or the Forth programming language (and its stack). Overall it is quite a toss up between the two. But if one were to ask me which brand to go with today, my answer would most probably be, "Go with TI. Get one of the TI-Nspire CX models if you are in high school or college and don't plan to use the calculator in a career, but get the TI-89 Titanium if you plan to keep using it beyond school and into your career." I am pleased with the design, speed, and ease of learning on the TI. ... show more
