For "here's a future technology development, let's see what it does to society", Bujold's Cryoburn (http://www.amazon.co.uk/Cryoburn-Vorkosigan-Saga-McMaster-Bujold/dp/1439133948) is an interesting read. It would be an interesting read anyway, of course, because it's Bujold, and Vorkosigan Saga at that, but the vote-rigging that happens as a result of commercial cryostatis is a concept that wouldn't have occured to me.
