HP released their latest graphic calculator, the 50g, last week and this thing is tech'd out to all hell. The can connect to this calculator via a variety of ways—infrared, USB, serial (you kidding me? Serial ports still exist?) and SD memory. According to Erica over at CNET News, this calculator can even calculate in Reverse Polish Notation. Now I don't have the slightest clue what the means, but it sure sounds fancy.

Additionally you can write your own programs and transfer them onto the calculator. As long as I can put solitaire on this thing, I'll be happy. $150. – Travis Hudson
