I read this back in 2004. It was one of those scifi classics I had meant to read for a while. I finally got to it, and it was definitely worth it. As it often happens, the edition I have does not match the covers here, so I just picked one that looked nice. I got my copy second hand, a nice one with a nice cartoon-like character on the cover that looks like a very good ad man. Very appropriate. Overall, this is one to read, and it is still very relevant today.
