- The display has a Pretty Print option (default), which is very helpful when inputting long formulas.
- Great for Statistics, which is why I bought it in the first place since that is my major in college.
- This is important if you are a college student. The math and statistics books all refer to the TI-83 when explaining how to perform the calculations using a calculator. So while the teacher is talking out loud walking the students step by step on how to perform a calculation, you're sitting there with the most powerful calculator in the class and out of luck. Then you have to scramble flipping thru the menu items to match the menu path of the TI-83, AND you're trying to learn the math at the same time. That happened to me in a statistics class and that wasn't fun at all! So be prepared for the inevitable; this is your warning. I recommend you study the upcoming textbook chapter ahead of time and learn how to perform those functions before you get to class.
- PDF files exist to explain the Flash applications loaded on the TI-89 Titanium. Unfortunately they are not easily found on the TI website. To get the PDF's, you have to follow the menu path as if you want to download the application. Then on the web page where you download the application, the PDF is there. TI should have also have placed the PDF in the "Documentation" section of the website. If I had not updated the application, I would not have known the PDF existed. Make sure you download the PDF for the TI-89 Titanium, not the PDF for the TI-89. Some functions are different. For statistics, be sure to download the PDF "Statistics with List Editor Guidebook For TI-89".
- I did the Operating System upgrade, but with a few bumps along the way. For example, I have Windows XP Pro SP2 on my PC and it doesn't recognize the driver when plugging in the USB cable. TI knows this and is part of the calculator-to-PC connection instructions on their website. So you'll have to uninstall the driver and then let Windows search for a driver. Eventually Windows found it but I got a horrific message saying the "Microsoft strongly recommends you backup before installing..." In fact, Windows set a System Restore point before installing the driver. The driver worked but why can't TI certify that driver with Microsoft so that message will not scare the heck out of the average user?
- Make sure you register before beginning the OS upgrade. You need to register to get any of the downloads, so do it as soon as you get the calculator.
- You'll notice that the dates listed in the "About..." menu in some of the Flash applications are almost the same as the dates listed on the TI website. Don't bother to download those because the applications are the same version. Don't know why TI lists a different date on the web page from the date displayed in the "About..." menu in some of the applications.
