Yeah its one of my favorites. A similar book written roughly around the same period by Aldous Huxley is defenitely recommended if you appreciated this one. It's called Brave New World. It presents the future as a dystopia based around conditioning and consumerism rather than the totalitarianism of Big Brother. It may even be closer to the actual outcome than 1984 is so far. Either way it is interesting comparing the two. Orwell was actually a student of Huxley when in college.

Huxley is the guy in the avatar; Im a bit of a fan.
