You can add Leonardo da Gimli to the list as well. He SEEMED conscious, but was merely operating within the parameters of his program as was explicitly stated. For the most part, the Doctor was meant to be the same thing, but operating for years outside of those parameters allowed a true form of sentience to evolve IMO. One would only wonder what would have happened had Soong gotten ahold of the Bynar's technology to simulate sentience (assuming that's what it was - granted, there's 20+ years between these efforts anyway, show time). While fundamentally separate approaches, I think they got the same results.
