Here is an interesting article forwarded to me by a friend who works in the Backbone arena. Read this article online at http://www.lightreading.com/document.asp?doc_id=4009 I am not making any commentary myself as to which is better because I don't work with either of one of these models so I don't know. I just found this interesting.
