One thing about this author - he has this quirk of making repeated mention of some new technology and technology is often a theme in his books. I'm OK with that, but I wish he would be a little more subtle about it. ALso, he tends to repeat phrases throughout his books a lot. I don't know if that's intentional (I hope so) but it bugs the crap out of me.
Other than that, I love his stuff. The plots are always very interesting and generally they focus on what could be a real moral ambiguity. I like that.
