TI-84 Plus C Silver Edition graphing calculator will be available this spring and for those of you who love your TI 84 Plus you will love that the transitions will be almost seamless as it has the same key placement, navigation and menus as your trusty TI 84 Plus. So why would you consider this one? Well, it too can be used on most standardized tests, it has a re-chargable battery, great color and enhanced screen resolution, back lit screen and an updated operating system. Upgrading is a very personal decision and only you can decide. For me, although I love my TI-84 Plus, I always like to get my hands on the next version for the enhancements and the color is pretty nice to have.
