Ti-89 is really useful if you know what is going on in your calculus classes but don’t want to do the homework, because it solves problems easily but obviously shows no work.

However, despite its many features, it is a little slower than 83 and 84 because you always feel a slight lag time after you press the enter button that doesn’t happen with the older models.
