The first three shorts, when initialy published, had a real "15 minutes into the future" vibe. Substantial ideas thrown away as quick asides gave it that "acceleration" vibe - a society with its finger mashed on the fast forward button. William Gibson is positively static by comparison.

Some of those throwaway ideas seem quaint now (there's some stuff about body modems I think?), but one of the interesting things about the book, to me, is the further away from "the present" it gets, the more like traditional SF it becomes: it slows down, gets more spaceopera-y. But those first three shorts were something special, and for me might be the best thing cstross has ever done. Right place right time I guess, like that album you first heard when you were fourteen.
