Pros: Attractive Design, Clear Display, Compact Size, Easy To Use, Long Battery Life, Quality Construction
it doesn't evaluate definite integrals correctly when at least one limit of integration is a variable.when performing matrix operations,it rounds the matrix entries to the nearest decimal form rather than displaying the exact fractional form.for example instead of displaying 2/3 it displays .66666. these are the problems that i have noticed so far.i like to comment more in the future

I absolutely love this calculator! Best one I've ever used. I think it can do absolutely anything. The only problem is that a LOT of professor's will not let you use it because of how powerful it is. Heck, most professors won't let you use TI-83's because of all the cheating that goes on. And the Voyage makes it even EASIER to cheat, not that I would of course. So in that context it could be a waste of money. But I don't regret buying one :D

A calculator so sophisticated with the worst display they could use. With the actual LCD displays, sensitive screens and rechargeable NiCd batteries, is out of my understanding why TI still uses this kind of display. Even cell phones have better displays to insert and show data. The contrast is not good enough and if you are under a filament lamp you can see the numbers with a ghost (two times the screen, due the shadow). If you use a notebook, cell phone and digital camera daily, you will not like this product. The resolution is not so good for the "textbook like" and to the "Advanced Large Screen Graphing" slogan. The pdf documentation is bad too, since I CANNOT PRINT the necessary pages.

I've had a HP48G and a HP49G in the past. Both were good calculators and I miss the RPN mode of entering digits in them. The TI200, as most of other calclators as the "normal" mode of entering digits: 2+2 ENTER (in that order), but I got accustomed to this fairly fast. The display is a bit harder to see compared to a HP49G, specialy under low-light conditions. The thing a like the most of this calculator is it's greater flexibility and ease of use for creating programs. The interface/commands for creating these small programs is similar to structured programming I was accustomed to in school, e.g. I've created a program to add Coulomb forces in vectorial form and another to calculate probabilities in a normal curve. It has many applications available to download and, as well as the HP, it has a large user community on the web. It is also fast, compared to the old models of HP (I'm not comparing it to the newer HP50) it solves numeric and symbolic integrals in less time. It is also very configurable and robust. The downside of this calc is that it does not have a pouch like the HP's... those pouches where great at keeping the calc safe from scratches and dirt. This unit only comes with a hard case that protects one side of the calc at a time. I've found a pouch that actually was a perfect fit for the calc: see my review of Belkin Neoprene Kindle Case (Fits 6" Display, Latest Generation Kindle)

I bought the Voyage 200 because a professor recommended it, and I must say it is the best investment a math major can make. This thing can do just about anything you need it to, and quickly! I've found myself in a situation where I need to verify whether a difficult problem is correct, and the Voyage 200 provides very reliable support in that aspect. The Voyage tends to oversimplify its output at times, but it's nothing that warrants a change in my opinion. I am utterly fascinated at the capabilities of this calculator.

Condition was not as "good" as portrayed. It works but looks a little banged up!

My son loves this calculator. It has helped him tremendously in his classes. His classmates and teachers are jealous!
