Talk of real calculators, I still have an HP-11C purchased almost 30 years ago. Being retired, I don't use it much these days, it was/is a wonderful little device, though it is RPN rather than Algebraic data entry, which is why I purchased it. This is offputting to some people. Current set of batteries have beern in calculator for close to 5 years. As memory serves, battery life, when I was employed and useing it regularly was about 3 years.
