Digital Cameras Photo Reviews of Texas Instruments Voyage 200 CalculatorCustomer Review: Extremely fine new form factor for the TI-89 and TI-92 calculators Summary: 5 Stars
I have owned top of the line graphing and scientific calculators from TI, HP, Casio, Sharp, etc. Back when I was a student, TI's were very cheaply made and often broke quite easily. This machine, the TI Voyage 200, is definitely not cheaply made and is definitely put together very well. It is also a good improvement over its predecessors with a different form factor, the TI-89 (and even an inprovement over the TI92) with more memory and with an improved keyboard and improved keyboard "feel" and a much better feature set, etc. The pros and cons as I see it are:
PROS:
1) It has all the standard regular and CAS (Computer Algebra System) features that we have come to expect on such a machine, plus many nice very detailed and topic as well as course specific APPS that are already preloaded and these can also be added in electronically and quite simply from the TI website. The interface with a computer is fast and easy to set up. For a good manual instead of the skimpy documentation provided by TI, just use the TI-89 manual and you will be just fine on its overall capabilities and operations.
2) It has a very nice calendar and note storage system for keeping track of coursework and daily workload assignments.
3) It is quite fast with a nice graphical interface and resultant plotting system. The resultant plots are high quality and with the many added features available for enhancement, these are very intuitive for the learning process.
4) The icon system for choosing where you want to be on the machine can also be converted to a much easier and quicker to navigate text-list system.
5) It has a nice and quite modern, large slate-like body design that is quite large and that sits very nicely both on a desk or a table as well in your hands.
6) It has a large amount of onboard main memory, plus additional Flash memory for tackling quite memory intensive problems.
7) This TI Voyage 200 machine is to the TI-89 Titanium as the Casio FX-9860g Slim is to the Casio FX-9860g. The much improved form factor on both these former machines is great for computational and viewing purposes, but the TI machine is much much larger and less portable overall than the Casio which is extremely portable and pocketable.
CONS:
1) There is no SD card slot as on the HP50g.
2) Integrals are completed by a table look-up process and not by direct manipulation so very little insight can be found by students as to why the result appears the way it does. On the HP50g, in step by step mode, much additional insight can be gained by the manner in which the integrals are performed for example.
3) The algebraic operating system is the only choice available on this machine which usually requires many more keystrokes to do a complicated problem.
4) The available programming languages are quite limited on this machine as compared again to the HP50g.
5) Some functions that you would readily expect to be available with a single key press require instead at least two key presses, but usually with only a single shift key press first.
6) The color coding choices are not as distinctive and easy to quickly recognize, but much better than on the TI-89 Titanium.
7) As with the HP50g, it require multiple batteries plus a backup coin cell battery to save everything briefly when changing the main batteries.
8) TI should also impliment a fine backlight system for viewing the very large TI Voyage 200 screen at low ambient light levels, as recently included on the Casio FX-9860g Slim version for example.
