Is there a way to set up a Smart Album for photos that have not be edited or adjusted? I looked for a parameter to do that, but can't find it. I know edited photos get marked and I could manually keyword the unmarked ones, but I wanted to see if you found a more automatic way of collecting together unedited photos in Aperture.

There is no way to do this with Aperture 1.5.1. I have seen it requested a number of times and could certainly use it myself. It's a pretty basic workflow requirement. Aperture should be able to filter and sort on any image attribute. The list view does give access to a column that includes the badges:

but alas sorting does not work on that column. So although there is a compact visual way of finding the unadjusted ones, it is not even possible to sort all the badged items to one end of the grid view.
