great calculator
I have been using a TI-85 since 1993. It served me fantastically! When looking to update my hardware I was looking for something to last me the next 15 years. While I have obviously left many models pass me by in the last decade and a half, I looked to either the Ti-89 Titanium or Voyage 200 to be my next calculator. In the end the features between the two seemed very similar to me. AT and SAT test requirements would have pointed me more toward that Ti-89t but that not being a requirement, I opted for the larger screen the Voyage 200 provides me. Overall, I love my choice and have only begun to tap its abilities. My only regrets are that I waited 15 years to upgrade... that, and I do miss printed documentation (although the provided PDF is easily searchable).

It's a Wow Calculator, The Thecnical Manual is on a CD to Save Paper
I Would disagree if this calculator has print its manual, because is over 2000 pages, and all are in PDF file. Beautiful calculator, very powerful. Bulky but necessary, wish that they could redesign its cover like sliding it. (like the TI-83, 84, 89). Wonderful. Would recommend.

Best calculator on the market
With large screen and QWERTY keyboard this calculator should be located in category of computers, but with size and price of calculators. QWERTY keyboard is essential if you want to do programming - doing this on multi-function keyboard of TI-89 is close to impossible, and PC tools that TI provides for programming are outdated and primitive.
Screen is the largest among calculators available on the market, with very good resolution and contrast. Be aware that size and weight are such that this device is rather desktop than pocket one. But... who needs to compute eigenvalues of a matrix when riding a subway?
I own practically all models manufactured by HP, TI, Casio and Sharp (including some highly historical items; I have such crazy hobby :), but this one is THE BEST
