I have been using hubiC in Windows and Linux without issues.

They give 25 GB, and respect your privacy (they are based on France).

I tried them but they did not offer any kind of access to previous versions of files which was a show stopper for me.

I started using hubiC because I need a replacement for Ubuntu One.

So far there's no perfect file cloud service, unless you want to also manage your own server.
