I found this book to be useful. I usually use Common Lisp, Ruby and Java for my work but I have had a long term interest in Clojure. Recently I have seen an uptick in customer demand for Clojure development so I have revisited Stuart's book and two MEAP work in progress Clojure books.
One issue that I am having with Clojure is the relatively poor stack trace information, even with the clojure-contrib ST utility. That said, I bet improvement comes quickly.
BTW, Stuart's Clojure in the Wild web cast is pretty good.
