so this is like the coolest calculator ever. sadly its probably not the best for high school kids due to its banning on the SAT and most likely some/all class exams. however, its capabilities are wonderful. mind you, you can go for the ti-89 titanium and get most/all of the voyage 200′s features and rock it on the SAT but if you can spend the extra dough on the 200. the screen is fantastic and the qwerty keyboard does come in handy. i used a ti-85 for about 12 years before i upgraded and im counting on the voyage 200 going for the next 12.
