I believe that, from an intellectual standpoint, a whole hive-mind/immortality deal would be a boon. Eternally experiencing everything the universe has to offer, all while sharing them with other immortal minds. Never knowing fear, doubt, or sorrow. Never finding oneself lost and alone. There are definite positives.
However, the romantic in me finds the idea horrific. The loss of one's unique identity, the inability to experience intimacies of any degree. The damning knowledge that the being you once were actually HAS died, leaving only the data it once carried to be cannibalized by an alien mind that holds no value or understanding for the tiny nuances that defined the original organism from all others.
To conclude my mini-tirade, I'd like to end with two points. First, I really should abstain from watching Zero Punctuation before giving my opinion. Second, I don't think I'd willingly chose to make that particular "deal with the devil." Living one's life, in my own humble opinion, only gains true value in knowing that someday there will come the inevitable ending. However, should the situation arise, and I find myself shackled for all eternity to an intergalactic robotic hive-mind, I suppose it's wise to make the best of things.
