Casio fx-82A

Let's take a moment to marvel at my calculator, the venerable CASIO fx-82a. I picked this up in high school when my chemistry teacher was going to get rid of it. Because even 15 years ago it was considered old. My favorite feature is the physical on/off switch.

If you wanted, you could wax all philosophical about the enduring value of something that still fulfills it's purpose.  Or you could talk about a society that would throw something out because replacements are so cheap.  I'll let you do all that.  I'm busy making a little party hat for my calculators 30th birthday party.
