overview
According to HP Calculator guru Eric Rechlin, the HP49G+ "appears to be better than the 49G in every single way -- the key legends have higher contrast (more attractive color, too), the screen is bigger, more memory is available, the keys are no longer rubber, infrared has returned, and the price has dropped $4."
