Apparently at one point, Office Depot had an ad for the Zune with a bad color representation of the item for sale.  The pic showed the Zune in this cool copper color.  Look at all those o's and c's.  Anyway, see the link at http://www.zunerama.com/zune-versions.php for a nice tour of the various Zunes that have been produced.  I wonder if there are any serious Zune collectors that have one or more of each.  That would be quite a collection.
