Heh, good question! I don't really think the brain is enough to "upload" a personality, though. The rest of the body matters. A lot. Like... A lot of "thinking" is done by the gastrointestinal system, even. And don't forget about hormones... So, uh, I'm having difficulties with the whole concept of separating consciousness from physical body. I'm at, it's an interesting concept in a story, but not in a "oh, yeah, if technology evolves a bit, we'll do that" way.
