I really wouldn't like to be a droid at all. Being a mechanical thing, with a pre-programed mind, I would not have a mind of my own, it would be a simulation, I would not be a conscious being. C3PO is not a person, he looks like one and sounds like one, but it's fake, he would not be able to really think. OK, maybe I've started a bit of a "AI - artificial inteligence" discussion here.
