U3 is a platform and Migo is a standaolne application. I have a U3 Drive and I also tried Migo with it and some other applications. I needed an application to sync my Outlook between different PCs since I don't have an exchange server and the only application that allowed me to do that on a U3 Drive was Carry it Easy +Plus http://software.u3.com/Product_Details.aspx?Produc tId=179&Selection=1&Lang=en-US&Position=ENHPFS2F The software also has 128 bit AES encryption and makes your data sufficiently safe. I can not say how the U3 encryption is since my U3 drive doesn't offer this.
