The collection has some interesting stories, some fall a little flat, others are just great.

I think missle gap is one of the more interesting ideas, even though I'm not especially amazed by the idea of an alderson disk. I liked the exploration of things like the slam missle being developed to their conclusion.

Snowballs chance is a funny little aside that I also liked. A colder war is good in it's exploration of the laundry universe for another angle.

unwired, is very obviously something that was done together with Doctorow. It has his style and tenancies all over it (it reminds me very heavily of Makers, with it's semi-preachyness and tendancy to ignore real world innovations to make the sci-fi seem more amazing)
