A bit late to the discussion, but a few general thoughts:
Deckers and Technomancers have much, much fun invading opponents' cyberware, doing things like turning off their eyes, turning off wired reflexes, bricking eyes, looping obscene images on their image link.
Corporate internal security can do sweeps of wireless traffic to detect cyberware in locations where no authorized personnel are supposed to be. What piece of 'ware is an infiltrator or weapons specialist willing to give up to avoid these while having their eyes, ears, internal weapons, foot anchors, etc. work at a higher capacity than wireless-off mode?
