That's the last of his that I've read, I thought it was okay. Stronger on concepts than execution. Of all the books involving nanotech, I think he has the clearest vision of where it'll go. The tools and nifty constructs from The Cassini Division by Ken Macleod were nice, but humanity is not going to go that way any time soon. Giant media walls, chopsticks with scrolling ads, and do-it-youself constructor units, that's where it'll be!
Plotwise the book is okay. You can tell just from the astonishing Depth that Stephenson had a lot of ideas, and then some! Some get better execution than others. Personally, I think he had too many characters, and several get lost in the shuffle as the book progresses. Especially towards the end it really starts to degenerate IMO. I can see how some parts reflected what was going on in others, but there was a lot that I was just going "huh?" over. Finally, it ends too quickly considering the slow pace of the rest of the book.
Oh, and if you didn't like the open end to Snow Crash, Diamond Age will drive you nuts. Utterly MASSIVE open ending to that sucker! It's like finishing Hyperion by Dan Simmons and realizing there's no sequel! That's really what I disliked the most about it.
Overall I thought it an okay read -- great on concept, fair on execution, as I said -- but the poorest of what I've read from him save The Big U. I still have to read Cryptonomicon and am greatly looking forward to that, whenever I'm able to finally get around to it.
