DesignBoom found this curious USB-stick concept made for sharing. On one side yousave all your work docs, and on the other you can upload your MP3s, private emails, love letters, games or even porn. Oh, don't act like you don't have any. This is only a concept design by designer Marc Julian Zech in Germany, but a good idea always finds its way into production. We'll just have to wait and see if this one does.
