Astonishingly powerful, but awful documentation,
By
This review is from: Texas Instruments Voyage 200 Calculator (Office Product)
The actual calculator itself is stunningly powerful. It is faster than the TI-92, the full keyboard makes it easier to work with than the TI-89, and the ability to solve, factor, work with imaginary numbers, give exact answers, as well as do all of these things symbolically, plus the amazing applications included (a version of Geometer's sketchpad!), make this the best calculator made by TI. Just beware that some standardized tests and some teachers will not let you use this calculator. The biggest drawback is the documentation that is supposed to help you utilize the power of this calculator. There really isn't any. There's a short manual that's included in the box, but it only gives you the broad overview of how to put the batteries in and how to turn it on and off. To find any information on how to, say, type something in that you want to factor, you have to load up the cd-rom, and hunt around on that thing to find the information you want. It's a huge hassle - if I'm at class, or work and want to be able to use some function, I have to wait to figure it out until I can get home and load up the cd-rom, find the right page, etc....not to mention that the documentation on the CD-rom isn't that helpful either. There's lots of discussion of stuff, but it is very hard to understand. A great calculator, but awful documentation that makes learning how to use all of its powerful functions frustrating and annoying.

Powerful little beast,
By Fitz the Robot (Cambridge, MA) - See all my reviews

This review is from: Texas Instruments Voyage 200 Calculator (Office Product)
Plain and simple, I love calculators. Yes, I have both Matlab and Mathematica running on my multiprocessor workstation but calculators have always had a special place in my heart. Since high school, I've firmly been in the HP camp and like many, I think the HP41C remains one of the finest calculators ever made. But the HP legacy started its sad decline with the 28C and the bottom fell out with the HP48G, perhaps the worst calculator HP has ever made. (It literally can take seconds to add two numbers... what could they have been thinking?)
All of that being said, I decided to venture into the TI camp, if only because they still take calculators seriously. I was dubious, however, because their machines seem designed for high school students rather than professional scientists/engineers, and this is reflected in the lack of high-end software packages available for them. Nonetheless, I don't think since the HP41 line have any calculators attracted so much interest or had so large a community built around them as have the recent TIs. The Voyage 200 is something of a tour de force. It is based on the Motorola 68000, the same processor found in the original Macintosh and many other popular computers. It is programmable both in TI Basic and in 68000 assembly, the latter of which has lead to a rather impressive library of available games and applications that all run amazingly quickly given their platform. This whole software world is somewhat muddled by the fact that TI has released a series of operating system upgrades and patches for this calculator and wading the compatibility waters is very confusing for the uninitiated. (For example, for HP aficianados, it is quite possible to run an extremely well done RPN interface on this calculator, but it requires that you find & download both the RPN assembly program and HW2 AMS 2 TSR support (h220xTSR) if you're using the latest version of the operating system, AMS 2.09. When was the last time you worried about what operating system your calculator was running??) Another troublesome point about this calculator is the documentation is shockingly bad. Really, it is just plain awful. It comes with a thin, almost useless manual, and you'll have to read through 20+ pages just to find out how to add 1+1. Haven't they ever heard of a "getting started quickly" guide? There are several hundred pages of manuals on CD and on the web, but in general, there are written very poorly indeed. Coming from the world of professionally written documentation for systems like Mathematica and Matlab, I realize just how lucky we are that those companies take documentation very seriously and write far simpler manuals for much more complex systems. All in all, however, I think the Voyage 200 is the best thing going in the calculator world today. It's wonderful to once again have a calculator whose capabilities are as much fun to discover as it is to use. I doubt I'll ever find time for assembly programming on this beast, but it warms my heart to know that I could.

The Voyage 200 is a Ti-89 made difficult,
By Dave (Houston, TX USA) - See all my reviews

This review is from: Texas Instruments Voyage 200 Calculator (Office Product)
My first graphing calculator was a TI-83 Plus. What a fantastic calculator! Its ease of use is a real credit to its designers. The TI-89 is more difficult to use than the TI-83, but its not too unnecessarily hard, especially considering its advanced features.The Voyage 200, however, is a real pain in the you know what. Not only is the Voyage absent a printed manual--this may be the new cost-cutting norm for TI products--but the electronic copy is hard to use. Instead of putting all the main information in one manual like the TI-83, the Voyage 200 design team spread its manual out across 28 individual PDF files, making it nearly impossible to print out a hard copy for reference when you're away from your PC. TI could argue that it was necessary considering the large volume of information, but after perusing the PDFs--replete with numerous examples of duplicated information--I'm sure it was really about a large lack of effort. With that scolding of the manual designers out of the way, let me say that the features of this calculator are really quite good. When it comes to graphing calculators, TI really does make the best. If you are considering the most powerful graphing calculator on the market right now, it would come down to the TI-89 or this TI Voyage 200. The Voyage 200 is suppossed to be backwards compatible with the TI-89, but I've already found programs that run fine on the 89 but won't run on the 200--I can't understand why since they both use the same Motorola 68000 processor. Personally, if I had it do over again, I'd probably pick the TI-89 because its more traditionally styled case is less conspicuous, its features are easier to use, and it's manual is better written and available in hard copy. But if you want a tiny built-in QWERTY keyboard, a slightly bigger screen, more flash memory, and are not bothered by difficult documentation, then the Voyage 200 is probably your best choice.

A word on documentation,
By Sandstone (Salem, OR United States) - See all my reviews

This review is from: Texas Instruments Voyage 200 Calculator (Office Product)
Recently received my Voyage 200, and am very pleased with the unit itself. As others have commented, the lack of a decent printed manual is a drawback.
Knowing that the TI-89 Titanium is functionally almost identical to the Voyage 200, I called Texas Instruments and ordered a TI-89 manual. Customer service was very friendly, the manual was cheap ($4.95 + s/h), and it arrived quickly. TI really should package this manual with the Voyage 200, and maybe they'll start doing it in the future. In the meantime, if you're getting a Voyage 200, just order an 89 manual from TI.

Better than HP49G and HP 48GX,
By A Customer
This review is from: Texas Instruments Voyage 200 Calculator (Office Product)
I own TI Voyage 200, HP 49G, and HP 48GX. HP 48GX comes with a very good equation library. Operation is OK. Not very difficult to learn. Plug-in hardware card is a plus because you won't delete purchased software accidently. Overall, HP 48GX is good but is a little bit old in this modern world. HP 49G has no equation library. Very difficult to learn and use. Insufficient of manuals, books, and resources. Calculation and graphing are often slower than Voyage 200 for the same problems. The answers to polynomial sometimes look like 0.9999998 but the Voyage 200 gives 1. Some people say HP 49G is the most powerful graphing calculator in the world. As an owner, I would say I don't know. Be aware, HP discontinued their research and development of graphing calculators sometime ago. TI Voyage 200 is the best. Bigger and better resolution viewer screen. Computer-like keyborad saves your time and efforts that compares to ALPHA ALPHA *****. The keyboard layout also avoids mistakes. Comes with many pre-loaded applications and you can download and transfer more by yourself. Very easy to learn, I did not spend too much effort and feel I can handle this calculator. Plenty of instruction manuals, books, and resources that are compatible to TI 92 Plus and TI-89. It is a pleasure to own and use Voyage 200.

Best Damn Calculator Ever!!!,
By
This review is from: Texas Instruments Voyage 200 Calculator (Office Product)
If anyone shows me a calculator who can take more than the 500th power of 2 without scientific notation and rounding -whole number displayed - i will buy that calculator.And the Voyage can pass that, depends on memory available. This thing insane to say the least. Do not buy it unless you are a math or physics or related major. Its over kill for trig or algebra. This thing does miracle in my labs for both chem and physics; and in multivariable calculus and differential equations and linear algebra courses it will give you what no book can: answers to every problem. It is so easy to check yourself with this. Thats why its called PLT- Personal Learning Tool. It has everything. The fact that it is a TI and succesor to the 92 Plus speaks for itself. Any HP is a spec of dust compared to this. I should point out that the Voyage 200 is an upgrade on the 92 plus. Thats why theres no printed manual. Uses same manual as TI 89. But if you go to [websit]you will find alot of stuff on using it.

Best calculator ever made,
By
This review is from: Texas Instruments Voyage 200 Calculator (Office Product)
I must confess that I own the TI-92 Plus, which lacks the on screen icons. However, I understand that they are otherwise the same. I own both the TI 83 and the TI-89, and this is far better.The 89 requires the Alpha key to enter text, a real pain. Plus, the 89 has 2-3 color codes per key, making it hard to read. The 92-Plus, and the 200 Voyager, eliminate that hassle for ease of entry and use. It is true that it is much larger, but so what? I have used it to actually try to learn math, and it has been very rewarding for me, eliminating drudgery. One other note of interest: this CAS program was originally written by the guys who wrote the Derive math program, a fabulous math tool. Texas Instruments purchased the company and now uses it in the TI series of calculators. Highly, highly, recommended.

Industry leading and remarkably capable for almost decade old technology,
By
This review is from: Texas Instruments Voyage 200 Calculator (Office Product)
This graphics calculator is really a small computer. Although the keys are too small for touch-typing, the qwerty keyboard allows an extremely large range of built-in functions to be entered with relative ease. If you don't remember the functions, the calculator provides menu access to the full list.
This calculator can perform both numerical and symbolic calculations, with answers in a mathematically exact form, or numerically rounded if desired. It can evaluate and solve both algebraic and calculus problems. It can graph single or multiple functions simultaneously or individually, where you can choose the type of display format, e.g., line, dot, square, thick, ... to distinguish each function. You can also plot sequences, etc. You can zoom in and out of a graph, reset the range of coordinates, trace the cursor along the curve to read coordinates, calculate maxima and minima, etc. TI provides ongoing support for this system, and if recent history with the earlier TI-92 and TI-92 Plus predecessor systems is any indication, will continue to do so even when a replacement becomes available. The Voyage 200 approaches, in many of the most widely used areas, the capabilities of more expensive mathematical software packages available for the PC, e.g., Maple, Mathematica, etc. In areas of overlap, this TI is almost always easier to use, although in less common mathematical domains its capabilities are much more limited or non-existent. The system's leading position, and the lack of effective competitors is both an attribute and a handicap. The Voyage 200 derives directly from the TI-92, TI's first symbolic calculator, released in the mid-1990s, which was then updated a bit to the TI-92 Plus in 1998. The Voyage 200 is essentially a cosmetic update, with increased flash memory, of the TI-92 Plus. For example, its display is still 240×128 and still monochrome. Clearly this, essentially decade old, system would benefit from a serious refresh. Display improvements in PDAs, cell phones, and other palmtop devices demonstrate the improved resolution currently available, and the introduction of color would significantly help in the presentation of multiple plots, etc. One hopes that TI management and engineers have already taken a serious look and are soon to release an upgraded system that includes not only the appropriate hardware improvements available for the display, memory, and processor, but extensions in the range of mathematical functions available, as has occurred with competing mathematical software systems. TI graphing calculators developed with TI's acquisition of Derive mathematical software some years ago. However, when the company announced that as of June 29, 2007 they would no longer sell Derive, apparently development stopped in 2006, there was/is an open question as to what TI's interest and capability will be to move their graphing calculator software forward in the near future. However, it is hard to fault a system that "got it right" from the start, has an incredible range of mathematical capabilities, is programmable, and allows for internet updates to its operating system and the installation of new applications. In spite of its age, this is still a remarkable industry-leading system that is really a pleasure to use.

Great Calculator - Terrible Software,
This review is from: Texas Instruments Voyage 200 Calculator (Office Product)
I have owned my Voyage 200 for several years now and use it for all sorts of things, from managing my investment portfolio to analyzing engineering data. This is a great calculator until the day comes that you have to update the operating system. I have been forced to update each time I have added a new application to the calculator, as new applications won't run without the latest version of the operating system. The update involves wiping out everything you happen to have saved in memory: programs, data, applications - everything. TI supplies an archaic software program to load the operating system and applications. It brings back memories of the 1980's when using a computer really did require a computer scientist. With enough time, effort and preplanning, it is possible to save your data and actually get it back onto the calculator close to the way it was to start with, but make sure you have plenty of time and patience pills.
With that said, this is still the best top of the line calculator there is. |
