I'd be in favour of non-ageing type immortality, so long as its cheap and readily available - if you're mentally and physically constantly renewed, I don't see the downside, particularly since you could still off yourself. Sure, if you just continued to age mentally there could be problems.
I'm not in favour of rich-people-only immortality, unless it's just the initial stages, before economies of scale made it available to everyone.
If we've developed sufficiently efficient/sophisticated robots, that could make immortality quite desirable - you could stop exploiting each other as much and educate each other instead, working together towards bigger goals for humanity.
