I think he missed wifi/cell phones, mostly. Had he thought of that, he would probably have explored these themes a bit more. In Neuromancer there is an episode (second half, when they have already moved away from Earth surface) where a character is targeted by a sort of drone/service droid. But I also sorta remember that in a subsequent story (I think it was Count Zero? Not sure anymore) one of the characters... cuts a videocall or something similar by actually yanking the cord out of the wall.
