All of the other very interesting banter aside, this is an interesting point.
I actually like my belay loop, because it orients the slots in my belay device in a vertical position, an ideal position in my experience.
I climbed for years with a BD Alpine Bod, and found it quite comfy.

I think that JM may be slightly mistaken about all the new Bod harnesses coming with a belay loop: http://www.bdel.com/gear/alpine_bod.php Don't forget there is a Bod, and an Alpne Bod.
