I hear ya, brother. Iron without, Iron within.
I don't wanna try and make this into a big "magic vrs. cyber" thread, but from my recent experiences (in sr4*), well-made sammies have a fair fighting chance against magicians; as long as they fight smart. The real kicker is LOS; if he can't see you, he can't hurt you. If he can see you, you can shoot him. Better yet my wired-friend, hit him before he throws up his "increased reflexes" spell and shank him in the ribs before it's his action

(that scene made me very happy). You could always blow him up with a tossed grenade.
I digress; my point is that in a stand up fight -Cyborg versus Spellcaster- the Magician can probobly blast the Razorguy (perhaps at a great cost in drain). But as shadowrunners, should we be betting on a "stand-up fair-fight"? I'd say both have a decent chance against each other.
It might be kinda cool to make cyberware a little more scary, and make everybody more like cyberzombies. Sort of a magical pollution due to the perversion of nature. In cyberzombies, I'm not sure what causes the background count and magic-hindering effects, but I think it has something to do with the scary-wicked-voodoo-magic ritual of darkness they use to tether the soul to the corpse-o-matic.
*My experiences as a player in SR3 made me beleive that there is no viable reason why the Awakened didn't enslave mankind and rule the Earth. I think the GM messed up the rules. But I think these concepts apply equally to both editions.
