Good run down, though I'll add one more: being a parent, wireless mice and keyboards get moved around and played with by young children. I often find my mouse managed to end up with all the toys, for instance, and if I left it on, random stuff gets clicked in the mayhem.
That said, the cable is still a non starter in the living room set since, y'know, tripping hazard. Funny enough, wireless headsets and controllers are much more important since kids (mostly toddlers) will get you tangled up managing them. When my daughter was a newborn, a wireless controller while rocking her back and forth let me play one handed games. Vampire Survivors got me through those long nights... lol.
Capital -> Dandy -> Swell -> Keen -> Groovy -> Rad -> Slayed (although I'd have picked Bussin').
I wish I knew more going back even into the nineteenth century. I recently read the Arsene Lupin books (1905), and although that's French translated to British English, I found the slang charming. Although I think cool was only used in regards to someone being calm and controlled...
