I use Mega Sync. It's the best service I've ever used for a "Dropbox" solution. Has support for every OS and mobile imaginable, plus web client is good. It also has a terminal application in which you can set up a WebDAV server, etc. etc. and really "get behind the wheel" if you want. If you don't, the device applications are great! Too many features to list. oh, and it's cheap! I keep everything in the default folders on a Mac / Linux fresh install (documents, music, videos, templates etc.) and sync the whole thing across computers except for desktop folder and downloads folder. My mailbox.org account came with a few GB of cloud storage. I'll put encrypted documents on there (like tax return) because it's soo easy to encrypt / decrypt on a browser with your GPG key with their web application. I use Mac devices (iPhone, Mac book) and have a Linux workstation.
