> Sure... but... the original $35 RasPi is closer to a modern RasPi Zero 1, which looks like it's selling for $45 - $50 on Amazon.
Yeah, because a second-hand 13-year-old computer is gonna last quite a long time.
I have a 60 year old computer attached to my Minuteman III and it's doing fine. A 13 year old computer that still works is a computer that still works. And if it's worked 13 years, then it might last another 13 years (unlike the Intel NUC that died after 18 months.)
A 13 year old computer is gonna use a lot more power than a RPi, that's for sure.
