I'll start off with what I don't care for: The essays at the back get a little repetitive. And it's funny reading them 40+ years after they were published and realizing that Asimov's dreams of the internet creating a more informed society missed rather badly.

But the stories themselves are great as always. Just fun, intriguing mystery boxes exploring themes connected to humans having created completely loyal and dedicated companions. Some of these are repeats from I, Robot, but excluding those, the standouts include the Bicentennial Man (a beautiful, heartfelt story) and Galley Slave (where Susan Calvin once again proves herself to be one of the best characters in fiction). Also, Feminine Intuition just had me cackling as I read it, with the men all being terrified of Susan (for good reason, she's so much smarter than they are).

In short, a wonderful collection of stories that is well worth the read.
