Bests & Worsts Reviews from Amazon

This is the most powerful scientific calculator in its class. If you're majoring in Engineering, or plan to major it, then you must get this one (or regular Ti-89) If you buy anything else for cheaper price, you'll have to spend $150 more to get this later anyway. (like me) However if your Math class will end up in Calculus or Algebra(i.e. if you're not going to learn Diff. equation or harder), you don't really need this, you will just waste extra $70 for the features that you will never use (or features that aren't allowed to use in exam) So think logically. It's really cool looking calculator and it got best software/hardware in the world. But if one is going to use it for simple graphic or solving polynomial equations, then it's really like simulating windows and playing Doom3 on NEC Earth Simulator.. Used Ti-83 will do as good for those..
