I am rewatching Star Was and it amazes me how interoperable their technology is. R2-D2 can just hook into the Death Star and begin reading data. There's even a funny scene where C3PO tells him to hook in to a port, only for R2 to be electrocuted. Their power ports are the same as their data ports, crazy! And Chewbacca, not exactly a paragon of intellect, is able to reassemble C3PO after he had been blown apart. And although his head is on backwards, he seems to be about the same as he was before being disassembled.

All of their technology is so advanced, and yet so... analog? It's beautiful, they get to just live their lives; they don't have to fuss about with documentation, closed source, outdated libraries, missing binaries, copyright, etc.
