Calculators can get / be WAY better than the TI-89. Look at the HP-50g for starters. (Insert TI vs. HP) / (Algebraic noation vs RPN) battle here

Why do you say the HP-50g is so much better? I own one, but because I also own a copy of Mathematica, I end up using the HP only for in-class exams and such. The hardest work it gets is a few tricky integrals.
