Review title: A must have
Product review: I've had mine for 18 years now and only changed batteries once and I bought it used from someone who couldn't grasp true logic calc functions of RPN for just a few bucks. I have dropped it many times, lost the !2C emblem, been rained on, kicked around in lockers, briefcases, floorboards and still keeps going. If HP ever stops making this model as is, they would be big fools. Anyone who ever wants to refinance or obtain loans must get and learn how to use it. Look on your banker's desk and chances are, there is an HP12C sitting there. Good handy tool for financial planning and bonds. I ought to buy another as a spare, but it just might be good for another decade or so. If only other HP products were as long lived as this calculator....
