This TI-Nspire Math and Science Handheld Graphing Calculator by Texas-Instruments, it's a great upgrade! This graphing calculator is a great uprgrade from the Ti-84 and Ti-89 series. It is more that worth the price. Not many people have them only because the Ti-84 are recommended by schools. They are recommended by schools because that is what their teachers and instructors know how to use and therefore are familiar with the operations. If you go with the Ti-Nspire, which I highly recommend, buy the Ti-Nspire for Dummies at the same time because you won't find many people in which to ask for advice. Within a week you will be light years ahead of all of the Ti-89 and Ti-84 users if you go through the dummies book
