LOL! They are horrible - a rip off - the only useful thing they do is make TI a bunch of money and give Algebra instructors a course section. How many times do regular people/students graph Algebraic equations, etc. outside a math class (or need to)? For 95% or more a standard calculator is just fine. And cost 90% less! :wavey:
