Now this would be a terrific post for Mobilewhack, if it had been around 30 years ago. Yeah, back then, a pocket calulator was a significant electronic investment. Nowadays, they are just some feature that is on our cellular phones.

Still, it is neat to have a simple device that you can just flick out with one hand, and run a quick calculation. I’m not certain if it is worth the $9.95 for something that you can do on your cellphone, unless you have to run that cell phone app with two hands.
