I recently did an audit of what spare USB and other cables I had. It turned out I had a lot of extra cables, most of them for items that I’d disposed of years ago (to recycling, of course.) In the end, I kept one of each cable that matched one I’m currently using with a peripheral attached to my computer, and took the rest down to the local recycling centre.
The worst part of all that excess? I was terrible at putting cables back into the box where they were supposed to go, so they ended up in odd corners getting in the way.
