I think my favorite part of the book was when it just turned into reading the political thesis on the essence of oligarichal collectivism or whatever it is. It's a great cynical parody of modern society, but I still think everyone misses the point is that it isn't so much about surveillance as it's about power through language.
You could just as easily have the book set in 1884 without any of the "future tech" and have basically the same plot going around with busybodies and peeping toms filling the rolls of the telescreens.
