I'd go, it would be awesome. Anything to get away from this dreary place.
I'd even go if it meant spending the rest of my life on a spaceship. partly because they'd a) use cryotech to keep us asleep until we get there or b) make ships nice enough for people to want to live in.
and there isn't much chance of us colonizing a rock/ice planet, as they're not really attractive to settlers are they?
besides, who on earth decided we have to jump on the starwars wagon and have planets that are 'city', 'ice', 'desert', 'jungle', 'water', etc. Is it all THAT hard to imagine a planet that has all of these landscapes... I know nerds don't have much in the way of a social life but they can't spend that much time in their mother's basements that they don't even know we have all of that stuff right here on earth...
