Anyone have a recommendation on a decent cloud-based file sync tool ala OneDrive? I use OneDrive extensively but there is no official client for Linux and the unofficial one has some major stability issues. I'm willing to change providers but not willing to put in the effort to roll-my-own.

I would also love to hear any success stories here. I converted my wife's Macbook over to Linux Mint somewhat recently and the best I could do was setup a shortcut to the Web version of her iCloud.
