Boxee is a desktop app currently available for mac and linux and offers a slick way to browse your movies, music, photos and other media. Rather than view movies by name, Boxee shows you images of the covers similar to browsing at Blockbuster. Photos can pull from your local drive or from Flickr. Music comes from your library and iTunes (non-DRM). The social aspects come from sharing between friends. Boxee helps you share recommendations with your friends in all media categories and this is where the business plan comes into play.
