 good and bad January 3, 2008

This calculator offers SOME improvements over earlier models. I find the statistical functions, especially regressions and distributions, and the calculus functions to be far more intuitive. You do not have to remember all the parameters needed to use these functions. The menus are very easy to understand and I do not find myself running to an inadequate help manual as I did on earlier calculators.
The higher resolution and bigger screen give a much nicer presentation. Problems are entered and solved in text almost exactly as you would see in a book. Graphs also look more accurate and detailed.
But there is one thing I DO NOT like on this calculator....THE BUTTONS!! The letter keys are small green keys nestled among the number and function keys. Hence you are constantly hitting the letter keys by accident and so you have to waste time correcting typing errors.
Another huge negative for me is the awkward nature of the graphing screen when finding roots, max/min points, and points of intersection. To find roots as well as max/min points you have to trace along the graph and when the tracer arrives at the point it provides the coordinates on the screen. However, the coordinates are often conflicting with the same space as the graph itself and hence you cant read the point. So you have to grab the coordinates and drag them to a spot on the graph where you can see it. And if you happen to trace past the point too quickly, the coordinates disappear and you have to trace back again. The same procedure applies to max/min points. Finding graph information with the TI84 and TI89 is far easier and quicker.
I also believe the snap on keyboard that converts the calculator to an 84 will eventually prove to be a bad idea. How many of those keyboards are going to get broken or lost?
Overall a decent calculator if you are willing to deal with some upfront frustration. But I do not see enough advantages yet to choose this over an 84 or an 89.

This is and easy to use user friendly device. its wider that the ti-83/84 but it has a much larger screen. the new keyboard is fantastic. the only problem i had with it is i have yet to find out if it has programing, but other than that its fantastics.

Very good calculator, Only thing missing is CAS. To use CAS you have to buy TI-Nspire CAS. Still the best product from TI. I like the snap in keypad system. Hope they come up with TI 89 keypad too, that will make it the dream calculator.
Overall awesome product for High school and college beginners. Good luck
