Here are links to some of the latest Longhorn screenshots.  So far, I am not impressed.  Filterable Explorer views, categories to complement folders (I think that is what I saw in the screenshots), desktops as windows, and merged window title and menubar are not exactly worth the upgrade.  Scoble, give us a screenshot that will pop my eyeballs, something that justifies all the hype.  Spill the beans or else!;-p
