If the technology for C3PO and Luke's bionic hand exist such androids must exist.

The technology is there, agreed, but we never see droids like that in the rest of the saga, while there are certainly parts where they might have come in handy. Personally, I don't think Terminator-like droids "fit" in Star Wars, it feels against the entire romantic concept of the saga.

Yeah, I'm familiar with Guri, but the movies should be the movies. The EU is an entirely different universe, one where Luke has sex with a ghost, half the Jedi Order seems to have survived survived their extermination, Palpatine has a cycloptic son and where apparently is some kind of superweapons-r-us where Kevin J. Anderson likes to shop for plots.

And what's wrong with Zam being just a human being? I agree that the shape shifter concept should be dropped because it's pointless, but why make her a droid? It doesn't really add anything.
