Because all of the inputs from the body are part of the consciousness, it would seem to me that, even if the upload were possible, the uploaded consciousness would be far from the original. Just guessing from the intuitive hip here, but I really think that much of what was the original having been eliminated would cause an immediate change and further differences would build up over time.

Ask our President, maybe he will tell you what it is like.

No, similar premise I take it?

In a future world people can be re-sleeved, their consciousness uploaded into a new body. The ultrarich can create their own clone or select a new improved body and can store backups of themselves. The religious can be coded so that they die for real (aren't re-sleeved). Of course people can die for real if their "Stack" is destroyed and no backups exist. The Stack is like a memory stick at the base of the brain. It's fairly graphic sex/nudity/violence, but it is very thought provoking

Started watching with a few friends - interesting concept, but we weren't overly impressed.
Does it get better after the first couple of episodes?

I think it does, but it probably not for everyone.
