I liked Swan, and part of the reason I liked her was that she sometimes wasn't completely likable
I have to say KSR continues his theme of what I think of as classic plot buildup that is eventually subverted. Here we have what I felt was a deliciously creepy development of the embodied qubes subplot, that... kinda turns out to be a nonissue in the end. He does this all the time. If I was more ambitious, I'd write up a little essay on it.
