I use phones. Landlines are handy when you’ve left your portables about and their batteries are dead. Ditto with cell phones. I’m just contemplating taking off the last jack that I never ran line to.
I dunno—a bunch of them made into a tech-vest? [I’m talking the insides here, not the boring cover]
use a pair for tecchy earrings—with little coils of the 4 different colors of wire hanging off the leads?
But, if you don’t use them, just take them off what is the big deal here?
