Dropbox recently (April 9,2014) and proudly appointed War Criminal Condoleezza Rice to its board of Directors. She actively helped Bush to lie us into the unprovoked and indefensible Iraq War. She also was an enabler of the Bush Torture program and much more. Condi Info here

Because I run Ubuntu, Google Drive, an otherwise good choice, is not straightforward for me. After checking all but the last 3 I found myself considering Copy or Spider Oak. At that point I decided that there was no reason not to do both and to maybe go with the Drive workaround for Ubuntu as well. After all, why not? If one goes down you still have one or more others. If you don't use too much storage your costs will vary between free and minimal, whether you run one or several.
