After reading all the threads, I'm still confused with this. So what does the official says about what cyberware counts as “obvious”?
What part of the following do you find unclear:
GreyWare always counts as obvious cyberware when
applicable and never provides wireless bonuses. If a piece of
cyberware cannot be obvious and has no wireless component,
it cannot be taken as GreyWare
Edit, let us look at a few examples:
Headware implants, for example, cannot be obvious and most of them does not provide wireless bonuses, so most of them they cannot be taken as GreyWare.
Cyberlimbs, for example, come in both obvious and non obvious versions. The obvious version can be taken as GreyWare while the non-obvious version cannot.
Dermal plating taken as GreyWare is clearly obvious even when you just look at it (while regular dermal plating is normally non-obvious when it comes to coloring and surface texture).
A fingertip compartment taken as GreyWare is clearly obvious (the compartment itself does no longer act as it have a -10 concealability modifier) and it always require a complex action to remove the item inside the compartment (instead of just a simple action as a non GreyWare wireless enabled fingertip compartment would have), but at least the item inside the compartment will still be completely concealed.
