CX (free to $19.99 per month) is a cloud-based syncing and storage back-up solution, similar to the well-known Dropbox, that gives you access to your files from virtually any Internet-connected device.
CX offers free downloadable software that works seamlessly on Windows and Mac, as well as free apps for the iPhone, iPod touch, and iPad.

The free basic account offers 10GB and all of the features.
