Query: Best HP calculator in years... don't settle for TI

This purchase was as much for nostalgia as it was for function. I'm an engineer from way back and still remember when the original HP35 and HP45 were in their heyday back in the 70's. I myself started with an HP25C and once I experienced RPN, I never looked back. My last HP was a HP15C, part of the last well designed and esthetically pleasing series before they started looking and feeling like TI calculators (cheap). It was disheartening to learn later that HP discontinued the 15C when Carly Fiorina became CEO of HP (one of the many reasons she did not get my vote for California governor). I purchased this for my great niece for Christmas since she is starting high school this fall (I also gave her mom her first calculator when she was in high school... HP of course). The new HP35s is a step back in the right direction... hoping they resurrect the HP15C (I would buy 2).
