USB stick in your pocket sounds nice but what happens when you drop your keys and it cracks or you get caught in a rain storm and it gets soaked?

Then the copies that exist on the USB are fried but the original that live at home on your desktop/laptop are fine?

Someone else made it similar comment, so I clarified the phrasing of my original post. The main backup of allll my decades of digital junk is independent and happens elsewhere.

Even if I had a USB-stick of magical capacity and reliability, I wouldn't want to have to remember to connect and disconnect it constantly.
