I first bought the HP-15C before my freshman year at Iowa State. I used it through my undergrad EE program and after school continued using it for years. The landscape layout, heft, and feel of the keys were all incredible. Years later I tried a TI-89 and really couldn't stand it, even though it had all the cool graphing foo and symbolic algebra which is really useful. So I distinguish between the usefulness of the features of the TI-89 and the qualitative feel of the HP-15C. Even later still I tried the HP-33 for a basic RPN calculator that I could lug around in my backpack and not worry about losing or damaging it. It's really light and certainly doesn't have the feel that the 15C does. The keys have a 'toy' feel to them that I don't like. All that to say that I probably will try this new 15C, but I'm skeptical. It probably won't have the same heft in the hand, nor the feel of the keyboard as the original. But hey HP, please surprise me!
