I enjoyed Brin's creation of a world very much like ours, where you can be in 2 places at once and do all of the things that you want to do. He carefully thinks out the consequences of the technology on society. Because the lifespans of the copies are so short, he also reflects on the nature of life and death.On another level, this is a satire of a traditional gumshoe mystery that is full of delicious puns, particularly on the word "ditto" (ie, he is a ditective). "Pundits" should discuss this book at length.
