Exactly- I have a desktop and a laptop and want the same experience on both. I do have file sync setup with Nextcloud so that is handled, but for some things a hosted version makes sense. I’ve come a long way from using briefcases on a 3.5 floppy to have my data where I want it.

Uncapped outlets can cause backfeeding, as can damaged cables; when I worked in the field a factory had a damaged coax feed and when one of their machines started up it would knock out the leg. Coax is basically a wireless signal that is stuck on the antenna (wire) rather than a digital signal like Ethernet, and it is a shared medium unlike DSL.
