I still have mine from '81. I remember my Dad taking me out to buy it. Now, being a fresh, college aged geeky kid, I wanted the -41, but we got the 15C, which, as a calculator, is more than adequate. It's just not the geek cred of the 41.<p>Certainly one of the best form factors ever for a calculator.<p>I like how its marked "Collectors Edition" so that collectors know it's not the collectible "non-Collectors Edition".<p>I hope its keyboard is still good. Only HP seemed to ever manage to make amazing keyboards.
