Life span of an HP Calculator

[nickapos]

I think this is one of the factors people are missing when they say that calculators are dead or obsolete replaced by computers or tablets or phones. Most calculators are build to survive either school related abuse or even better harsh working environments. They are build to last decades.

I could not afford hps back in the days but I still have my university Casio and sharp calculators they are more than 30 years old and I don’t remember ever changing a battery. I gave my sharp to my nephews who are now starting high school.

Also I have got quite a few second hand hps that are in pristine condition.
