Book review: Land of Lisp

I'm probably going to buy this, but would anyone be able to explain the state of programming Lisp on Mac OS X?

I seriously cannot wait for this book to arrive in the mail.

I'm reading it right now, and it's definitely fun. He doesn't glamorize Common Lisp (instead pointing out some design quirks) but his enthusiasm is still totally infectious. I think the video on the book's site captures the spirit of the book wonderfully.

This book makes me wonder why all "serious" material isn't presented in such a clear and entertaining manner. Five stars.
