In an effort to become more organized and utlitilze all the tools I have available to me... Dropbox, GoggleDocs, OnLive Desktop, Evernote, CloudOn...what the heck is the difference? Do you use them together or are they all different individual things? I am not that techo savvy so trying to decipher this is needless to say, overwhelming! While using my iPad, I want to have access to a Word document. I want to be able to make any changes necessary and then save it. Being able to access it without a wifi connection would be a huge benefit.
