Opti: that may be what you intended, but what was actually printed was:
"If a piece of cyberware cannot be obvious and has no wireless component, it cannot be taken as GreyWare." Which by standard rules of english grammar (and formal logic, for that matter) pretty clearly means that if it can be obvious OR it normally has a wireless component, it can be greyware. (notA AND notB = notC implies that C=A OR B).
Sounds like something for the errata team (and the Missions team), because most people won't be looking in this thread, they'll just be reading the book.
Another good clarification would be whether wireless functionality means specifically get a note of a wireless on bonus, or if it is literally any wireless functionality. For example, I don't think cyber-eyes get a wireless bonus, but image link may normally operate through wireless connections. So do eyes qualify, if made obvious?
I'd love to see some suggestions from people on what 'ware could be made to work with this. Depending ont he question above maybe eyes or ears. Limbs, muscle replacement, dermal plating and bone-lacing are all clearly out. Anyone have ideas on how wired reflexes could be made obvious?
