I think my favorite Ian book is "Terminal Cafe", which deals with a world transformed by nanotechnology. I paste:

-------
Watson's Postulate: Never mind turning trash into oil or asteroids into heaps of Volkswagens, or hanging exact copies of Van Goghs in your living room, the first thing we get with nanotechnology is immortality."

Tesler's Corollary: The first thing we get with nanotechnology is the resurrection of the dead.
