4 out of 5 stars A great calculator though still some flaws   July 28, 2004
 26 out of 27 found this review helpful

The TI-89 titanium is a very good calculator.
I also own a HP-49G and the TI is way better; the interface is so well defined... it's almost as a desktop.
Compare that to the HP-49G... it's like the command-line interface!
There are a couple of but's though:
First of all, the "2nd" labels on top of the keys are in a soft blue, almost unreadable. This is a very big design flaw.
Second, I don't like the screen a lot. Sure, it's large. Sure, you can set contrast. But if you are looking at it from an angle, it stinks. You can't set high contrast when looking it from an angle, as it just makes things worse. And believe me: if you work with an calculator, nine out of ten times you will be looking at the screen from an angle.
Lastly, why does TI refuse to put in a proper equation editor? The HP has one, and I find it personally very helpfull.
Sure, you can buy an add-on for $15 from TI. And yes, there are freeware equation writers too. So why not give it away then?
Concluding: don't get me wrong. This calculator is a very good performer, and I think the best that money can buy. Just wish they would have made it perfect...

5 out of 5 stars The extra $$ is worth it.   July 16, 2004

I have used many calculators in the past, but the TI-89 Titanium is the best ever. The words are not hard to read at all, as some would believe, and the symbolic manipulations are just like magic. As a student who is stepping into Algebra 2, and preparing to finish up AP Calculus BC, Calculus III, Differential Equations, Linear Algebra, and AP statistics, everyone else who has been in my situation has bought a TI-89, or a similar calculator with CAS. This calculator is well worth the $20 more than the TI-84 Plus Silver Edition, since interchangeble faceplates don't really appeal to me, and I really need some symbolic manipulation features to help me during Algebra II and all the other courses.


3 out of 5 stars Cannot see   June 28, 2004

I just got my TI-89 Titanium and it is a fine machine as you would expect with one exception. The blue lettering on the metallic background makes the characters almost impossible to read. This is very frustrating when you frequently need those functions. If you look at the older TI-86 the characters are bright yellow or blue over black and are easy to see. This may seem a bit picky but being able to see what you need is critical. I think we have reached the ridiculous point where style is getting in the way of utility. How in the world did this problem get past everyone? Anyway it is a great calculator but always carry a magifying glass strapped to it's back.


5 out of 5 stars Quality Calculator   June 18, 2004

I've used the regular TI-89 in the past, but I never owned one. I always used loaners from my high school. But now I'll be at college, so I need my own calculator. I just bought a TI-89 Titanium and I am very impressed. It has all the things that were good about the TI-89, plus a USB port, more memory, and a sleek new design. It is a beautiful piece of engineering.

If you've never used a graphing calculator and are thinking of just using a computer to do your work, you'll find that a calculator is much easier to work with. The TI-89 Titanium has a very intuitive design that only requires a couple clicks to factor, integrate, solve equations, graph, or access any of the built-in programs, like the calendar or the address book. It is small enough to fit in your pocket and carry around with you wherever you go.

The thing is also built rock-solid. I've dropped TI-89's in the past with no ill effects and the Titanium feels just as solid. The cover seems a little tighter than the TI-89's cover, but as I use it, I am sure it will slide a little easier.

The TI-89 Titanium is only $20 more than the old TI-89 and I've heard that the new HP calculators are not that great (just read the reviews of the 49G+). Plus, I've never even seen someone using an HP calculator and it's nice to be able to share programs with other people using a TI-89. If you're in the market for a graphing calculator, the TI-89 Titanium is definately the one to buy.
