Computer World magazine has a review (http://www.computerworld.com/action/article.do?command=viewArticleBasic&articleId=9043838&pageNumber=1) of Leopard already. Nothing specifically about our interest, but the section on "Core Technologies" might give some interesting thoughts to the more technical people here.

Links to the Pogue and Mossberg reviews of Leopard as well:
